Final answer:
Mr. Pirzada lived in Bangladesh when the story begins. East Pakistan, which would later become Bangladesh, was part of the Muslim state of Pakistan after the partition of British India in 1947 and gained independence in 1972.
Step-by-step explanation:
The country where Mr. Pirzada lived with his family when the story begins is Bangladesh. This is reflected in the historical context provided by the question. Following the end of British colonialism in South Asia in 1947, East Pakistan was one of the two areas that made up the Muslim state of Pakistan after the partition.
It is important to note that East Pakistan became the independent country of Bangladesh in 1972 after a civil war and the Indo-Pakistan War. Moreover, in a related historical note regarding South Asia, Rohingya refugees from Myanmar sought shelter in 2017 in Bangladesh, not Pakistan, the United States, or Germany, as Bangladesh shares a border with Myanmar.
