Final answer:
The two areas that became separate Muslim majorities after the partition of British India in 1947 were West Pakistan and East Pakistan, which eventually became Pakistan and Bangladesh, respectively.
The correct option is 1)
Step-by-step explanation:
The partition of India in 1947 by the British Empire led to the creation of two separate Muslim-majority areas: West Pakistan and East Pakistan.
These two regions were parts of what was formerly British India and were partitioned based on religious demographics, with the aim of creating a separate nation for Muslims. West Pakistan corresponded to the western part of India, while East Pakistan was carved out from the eastern side.
This partition resulted in significant displacement and violence as people migrated to join the new nation that matched their religion. Eventually, East Pakistan declared independence from West Pakistan after a bloody conflict, becoming the country known today as Bangladesh in 1972.
