At the time of the partition of India, which areas were designated as West and East Pakistan?

Muslim-majority areas in the west and east of British India

The correct answer is Option 1 - Muslim-majority areas in the west and east of British India

It was decided that what was till then known as ‘India’ would be divided into two countries, ‘India’ and ‘Pakistan’. Such a division was not only very painful, but also very difficult to decide and to implement. It was decided to follow the principle of religious majorities. This basically means that areas where the Muslims were in majority would make up the territory of Pakistan. The rest was to stay with India. The idea might appear simple, but it presented all kinds of difficulties. First of all, there was no single belt of Muslim majority areas in British India. There were two areas of concentration, one in the west and one in the east. There was no way these two parts could be joined. So it was decided that the new country, Pakistan, will comprise two territories, West and East Pakistan separated by a long expanse of Indian territory. Secondly, not all Muslim majority areas wanted to be in Pakistan. Khan Abdul Gaffar Khan, the undisputed leader of the North Western Frontier Province and known as ‘Frontier Gandhi’, was staunchly opposed to the two-nation theory. Eventually, his voice was simply ignored and the NWFP was made to merge with Pakistan.
