Who led the popular struggle against West Pakistani domination?

Sheikh Mujibur Rehman

The correct answer is option (3) - Sheikh Mujibur Rehman

Bangladesh was a part of Pakistan from 1947 to 1971. It consisted of the partitioned areas of Bengal and Assam from British India. The people of this region resented the domination of western Pakistan and the imposition of the Urdu language. Soon after the partition, they began protests against the unfair treatment meted out to the Bengali culture and language. They also demanded fair representation in administration and a fair share of political power. Sheikh Mujib- ur Rahman led the popular struggle against West Pakistani domination. He demanded autonomy for the eastern region. In the 1970 elections in then Pakistan, the Awami League led by Sheikh Mujib won all the seats in East Pakistan and secured a majority in the proposed constituent assembly for the whole of Pakistan. But the government dominated by the West Pakistani leadership refused to convene the assembly. Sheikh Mujib was arrested.
