Answer: Bimala Prasad Chaliha
Notes: The Assamese Official Language Bill was introduced on October 10, 1960, by the government under Chief Minister Bimala Prasad Chaliha. The bill passed later that month and established Assamese as the state's official language, while also allowing for the temporary use of English and providing safeguards for other linguistic groups. Chaliha was a key political figure who significantly influenced Assam's language policy during his tenure."
