Correct Answer:
A. Sheikh Mujibur Rahman
The Agartala Conspiracy Case was a pivotal political event in Pakistan's history, particularly in East Pakistan. The case was primarily against Sheikh Mujibur Rahman, the leader of the Awami League. In 1968, the Ayub Khan government accused Mujibur Rahman and 34 other Bengali political and military figures of conspiring with India to achieve the secession of East Pakistan.
- Ayub Khan was the President of Pakistan at the time and the head of the government that initiated the case, not an accused party.
- Zulfiqar Ali Bhutto was a prominent political figure in West Pakistan but was not directly implicated as an accused in the Agartala Conspiracy Case.
- Therefore, 'None of these' is incorrect as Sheikh Mujibur Rahman was the central figure.
