Who was the first Chief Justice of Pakistan to take oath under the 1973 Constitution?

Correct Answer: A: Hamoodur Rahman

Explanation: The correct answer is Hamoodur Rahman, who was the first Chief Justice of Pakistan to take oath under the 1973 Constitution. Hamoodur Rahman was a key figure in Pakistan's judicial history, serving as the Chief Justice from 1972 to 1975. Options like Yaqub Ali Khan and Muhammad Munir refer to other judges of the time, while A.R. Cornelius was a prominent judge but not the first Chief Justice to take oath under the 1973 Constitution. The 1973 Constitution is an important topic in FPSC, CSS, and NTS exams, particularly in questions about Pakistan's constitutional history and judicial framework.
