Correct Answer:
A. Ch. Rehmat Ali
The name "Pakistan" was coined by Chaudhry Rehmat Ali in 1933. He was a Pakistani nationalist who proposed the name in his pamphlet "Now or Never; Are We to Live or Perish Forever?". The name is an acronym for the regions of Punjab, Afghan (North-West Frontier Province), Kashmir, Sindh, and Baluchistan. Muhammad Ali Jinnah (B) was the founder of Pakistan but did not coin the name. Liaquat Ali Khan (C) was Pakistan's first Prime Minister. Hafeez Jalandhari (D) is known for writing Pakistan's national anthem. Thus, Ch. Rehmat Ali is the correct answer.
