Lithium is a critical mineral used in batteries for electric vehicles and renewable energy storage, making its production geographically significant.

Step 1: Identifying Major Lithium Producers

The world's lithium production is concentrated in a few countries known as the "Lithium Triangle" (Argentina, Bolivia, Chile) and emerging producers like Australia and China. As of 2024, Australia has surpassed traditional producers due to massive mining operations at facilities like Greenbushes.

Step 2: Comparing 2024 Production Volumes

Australia's lithium output in 2024 reached approximately 60,000 metric tons, exceeding Chile (~440,000 tonnes historically but with declining production) and Argentina. China processes significant lithium but primarily relies on imported raw materials rather than domestic mining.

The answer is (B) Australia — it is currently the world's largest producer of lithium as of 2024, driven by expanded hard-rock mining operations and increased global EV demand.

# Solution: Landlocked Countries and Their Borders

A landlocked country has no coastline and is completely surrounded by other nations, with the number of bordering countries varying significantly.

Step 1: Understanding Landlocked Countries

Landlocked nations are isolated from oceans and depend entirely on neighboring countries for maritime access. China, despite being a major world power, is landlocked in its western regions but actually has extensive Pacific coastlines—however, the question refers to countries completely surrounded by land borders.

Step 2: Analyzing Border Countries

China shares land borders with 14 nations: Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Bhutan, Myanmar, Laos, Vietnam, Mongolia, and North Korea. This makes it tied for one of the highest numbers of bordering countries in the world.

Zambia borders 8 countries, Niger borders 7 countries, and Nepal borders only 2 countries (China and India).

In 2023, Nicaragua announced its official withdrawal from UNESCO (United Nations Educational, Scientific and Cultural Organization), becoming one of the few countries to exit this major international body. This decision was announced by the Nicaraguan government as part of broader diplomatic shifts.

Step 2: Verify Against Other Options

China remains an active UNESCO member, the United States rejoined UNESCO in 2023 (after previous withdrawal), and India continues as a participating member. Only Nicaragua formally announced its withdrawal during 2023.

Final answer: (A) Nicaragua
