The correct answer is C: 1964. Khawaja Nazimuddin, a prominent political figure in Pakistan, passed away on October 24, 1964. His death marked the end of an influential career that saw him play crucial roles in the nascent years of Pakistan. He was the second Governor-General of Pakistan, serving from 1948 to 1951, and subsequently became the second Prime Minister of Pakistan, holding office from 1951 to 1953.
A: 1962 is incorrect. While 1962 was a significant year in Pakistan's political history due to the promulgation of the new constitution by Ayub Khan, it was not the year of Khawaja Nazimuddin's demise. He was alive and observed the political developments of this period.
B: 1963 is also incorrect. Khawaja Nazimuddin was still alive in 1963. He continued to be a respected figure in the country, even after his active political career as Prime Minister had concluded a decade earlier. His death occurred the following year.
D: 1965 is incorrect. The year 1965 is notably associated with the Indo-Pakistani War. Khawaja Nazimuddin had already passed away in 1964, a year prior to the outbreak of this major conflict. Therefore, any political or social events of 1965 occurred after his death.
Khawaja Nazimuddin is remembered for his statesmanship and commitment to constitutionalism during a turbulent period in Pakistan's history, and his passing in 1964 was a loss for the nation.
