This question examines an important Bihar General Knowledge fact: “In which year was the state of Bihar formally separated from Bengal?” The correct answer is 1912. Bihar was formally separated from Bengal on March 22, 1912, and this date is celebrated as Bihar Diwas (Bihar Foundation Day) every year. Prior to 1912, Bihar was part of the Bengal Presidency under British India. The partition of Bengal in 1905 by Lord Curzon divided Bengal into two parts — East Bengal and West Bengal — but Bihar remained part of Bengal Presidency until 1912. The year 1912 is one of the most important dates in Bihar's administrative history and is frequently asked in all Bihar state-level competitive examinations.
