Correct Answer:
D. Air Vice Marshal Allan Perry Keene
The first Commander-in-Chief of the Pakistan Air Force (then Royal Pakistan Air Force) was Air Vice Marshal Allan Perry Keene. He was a British officer who served from 1947 to 1949, playing a crucial role in establishing the nascent air force after Pakistan's independence. Air Marshal Frank Murphy was also a British officer but served later. Air Marshal Asghar Khan was the first native Pakistani to hold the position, but not the first overall. Air Vice Marshal Zafar Khan is not recognized as the initial C-in-C.
