Which of the following statements is incorrect about Sheikh Mujib-ur Rahman?

In 1975 Sheikh Mujib got the constitution amended to shift from a presidential to a parliamentary form of government.

The correct answer is Option 3 - In 1975 Sheikh Mujib got the constitution amended to shift from a presidential to a parliamentary form of government.

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.

The government of India supported the demand of the people of East Pakistan for their independence and helped them financially and militarily. This resulted in a war between India and Pakistan in December 1971 that ended in the surrender of the Pakistani forces in East Pakistan and the formation of Bangladesh as an independent country. Bangladesh drafted its constitution declaring faith in secularism, democracy and socialism. However, in 1975 Sheikh Mujib got the constitution amended to shift from a parliamentary to a presidential form of government. He also abolished all parties except his own, the Awami League. This led to conflicts and tensions. In a dramatic and tragic development, he was assassinated in a military uprising in August 1975. The new military ruler, Ziaur Rahman, formed his own Bangladesh National Party and won elections in 1979. He was assassinated and another military takeover followed under the leadership of Lt Gen H. M. Ershad.
