Correct Answer:
A. Ghulam Ishaq Khan
The question concerns the presidential succession in Pakistan following a significant national event.
- Correct Option A: Ghulam Ishaq Khan is accurate. Following the tragic death of President General Zia-ul-Haq in an air crash on August 17, 1988, Ghulam Ishaq Khan, who was serving as the Chairman of the Senate at the time, constitutionally assumed the office of President of Pakistan.
- Distractor B: Farooq Leghari became President much later, in 1993.
- Distractor C: Muhammad Rafiq Tarar served as President even later, from 1998 to 2001.
- Distractor D: None of these is incorrect, as Ghulam Ishaq Khan was the immediate successor.
Knowledge of Pakistan's political history and constitutional succession is essential for answering such questions.
