Who among the following led the popular struggle against West Pakistani domination over the eastern region of Pakistan?

Sheikh Mujib-ur-Rahman

The correct answer is Option (2) → Sheikh Mujib-ur-Rahman

Sheikh Mujib-ur-Rahman was the leader of the Awami League and a key figure in the movement for autonomy and, eventually, independence for East Pakistan. His "Six-Point Movement," which called for greater autonomy for East Pakistan, gained widespread support and was seen as a challenge to the central government in West Pakistan. The repression of this movement, including his arrest, led to the 1971 Bangladesh Liberation War and the creation of Bangladesh.
