The Statue of Liberty is a colossal neoclassical monument gifted by France to the United States as a symbol of friendship and freedom.

The statue was designed by French sculptor Frédéric Auguste Bartholdi and engineered by Gustave Eiffel (famous for the Eiffel Tower). It was conceived as a gift from France to commemorate American independence and the alliance between the two nations.

France gifted the statue to the United States in 1886. It was officially dedicated on October 28, 1886, on Liberty Island in New York Harbor. The Americans built the pedestal, while France provided the statue itself as a token of international friendship.

- England: While an important ally, England did not gift the statue

- Germany: Had no role in this gift

- Italy: Though a European nation, Italy did not contribute to this monument

Therefore, the answer is B) France — the Statue of Liberty was gifted by France to the United States.

RBI is the central banking authority of India, responsible for monetary policy and financial regulation.

RBI stands for Reserve Bank of India. It is the apex monetary authority established in 1935 under the Reserve Bank of India Act, 1934.

The Reserve Bank of India manages currency circulation, implements monetary policy, regulates commercial banks, and maintains financial stability in the country.

- Rural Bank of India: Not the correct expansion; rural banking is handled by cooperative and regional rural banks under RBI supervision

- Regional Bank of India: Incorrect; RBI is a national central bank, not regional

- Regulated Bank of India: Incorrect terminology; RBI is the regulator, not the regulated entity

Therefore, the correct answer is A) Reserve Bank of India.

Mars is commonly known as the Red Planet due to its distinctive reddish appearance caused by iron oxide (rust) on its surface.

Mars appears reddish or rust-colored when observed from Earth, which is why it earned the nickname "Red Planet."

The red color comes from iron oxide (rust) present abundantly in the Martian soil and rocks, giving the planet its distinctive hue.

- Venus is yellowish/bright white (covered in thick sulfuric acid clouds)

- Jupiter is brownish/orange with visible bands

- Saturn is pale yellow with prominent rings

Therefore, the answer is C) Mars — the Red Planet.

ISRO (Indian Space Research Organisation) is India's national space agency, and its headquarters location is a direct GK fact to recall.

Therefore, the correct answer is B) Bengaluru.

The President of India is the constitutional head of state, and Dr. Rajendra Prasad was elected as the first person to hold this office after Independence.

Note on other options:

- Jawaharlal Nehru was the first Prime Minister (executive head), not President

- Sardar Patel was Deputy Prime Minister and Home Minister

- B.R. Ambedkar was the chief architect of the Indian Constitution

Therefore, the answer is B) Dr. Rajendra Prasad

The seven continents vary greatly in size, and Australia is the smallest among them.

The seven continents in order of size are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.

- Australia: approximately 7.7 million km²

- Antarctica: approximately 14.2 million km² (larger than Australia, though mostly ice)

- Europe: approximately 10.2 million km²

- South America: approximately 17.8 million km²

Australia with 7.7 million km² is smaller than all other continents, making it the smallest continent by land area.

Therefore, the answer is C) Australia — the smallest continent in the world.

Speed of light in vacuum is a fundamental physical constant that remains the same regardless of the observer's reference frame.

The speed of light in vacuum (denoted as 'c') is the fastest speed at which energy or information can travel through space. This is a universal constant established by Einstein's theory of relativity.

The experimentally determined speed of light in vacuum is approximately 299,792,458 m/s, which is commonly rounded to:

- Option (A) 2×10⁸ m/s — too low, doesn't match experimental data

- Option (B) 3×10⁸ m/s — matches the accepted standard value

- Option (C) 4×10⁸ m/s — too high

- Option (D) 1×10⁸ m/s — far too low

This value is used in all physics formulas involving light, such as Einstein's E = mc² equation and electromagnetic wave calculations.

Therefore, the speed of light in vacuum is 3×10⁸ m/s

Vatican City is an independent city-state located entirely within Rome, Italy, and is the smallest country in the world by both area and population.

- Vatican City: 0.44 square kilometers (approximately 110 acres)

- Monaco: 2.02 square kilometers

- San Marino: 61.2 square kilometers

- Liechtenstein: 160.5 square kilometers

Therefore, the answer is C) Vatican City - the smallest country in the world at 0.44 sq km.

The national animal of India is an important part of Indian heritage and symbolism.

India adopted the Tiger as its national animal in 1973, replacing the Lion. This decision was made to recognize the tiger's significance in Indian culture, mythology, and wildlife conservation.

The tiger holds special importance because:

- It is featured prominently in Indian art, literature, and folklore

- It represents power, grace, and the country's wildlife wealth

- India launched Project Tiger in 1973 to protect this endangered species

- Elephant: National heritage animal (not national animal)

- Lion: Appears on the state emblem but is not the national animal

- Leopard: Found in India but not designated as national animal

Therefore, the answer is C) Tiger — officially adopted as India's national animal in 1973.

Russia is the largest country in the world by area, covering approximately 17.1 million square kilometers.
