# Historical Partition of Bihar and Orissa
The British colonial administration partitioned the combined presidency into separate provinces based on administrative efficiency and regional identity.
Step 1: Understanding the Original Configuration
Before independence, Bihar and Orissa were administratively combined as a single province under British rule. This unified region had diverse geography, languages, and cultural identities that justified eventual separation.
Step 2: The Separation Date
On 1 April 1936, the British colonial government officially separated Bihar from Orissa, creating two distinct provinces. This administrative division recognized Orissa's distinct Odia linguistic and cultural identity, while Bihar remained with its Hindi-speaking majority population.
The correct answer is (B) 1 April 1936. This partition occurred during the British Raj, well before Indian independence in 1947, and established Bihar as a separate administrative unit with its own governance structure.
