Answer:
a. bangladesh
Explanation:
The country we now know as Pakistan was initially part of India. Today's Pakistani history begins during the period when India was a British colony, at which time some Muslims began the process of obtaining a sovereign state. Allama Iqbal (writer and philosopher) and Muhammad Ali Jinnah (who became leader of the movement) were the proponents of the idea of a Muslim state. Therefore, Pakistan was founded in 1947.
From the founding of the Pakistani state until 1971, western Pakistan was united with eastern Pakistan, from which it was 1,700 km apart, but the latter, with the support of India, managed to separate from the former and formed a new country called Bangladesh.
