Correct Answer:
B. 1985-1988

- Step 1 (Senate Leadership): Ghulam Ishaq Khan was elected as the Chairman of the Senate in March 1985 during the transition back to civilian politics.
- Step 2 (Sudden Promotion): He held this post until August 1988, when President Zia-ul-Haq passed away in a plane crash. As Senate Chairman, Khan automatically became the acting President of Pakistan based on constitutional rules.
