Correct Answer:
C. Aswan
Sir Sultan Muhammad Shah, commonly known as Aga Khan III, was the 48th Imam of the Nizari Ismaili community. He was a significant figure in the 20th century, advocating for Muslim rights and contributing to various social and educational causes. He is buried in Aswan, Egypt, in a mausoleum overlooking the Nile River, a site that has become a pilgrimage destination for his followers.
- Cairo is the capital of Egypt, but not the specific burial site of Aga Khan III.
- Karachi is a major city in Pakistan with a large Ismaili population, but it is not where Aga Khan III is interred.
- Istanbul is a historical city in Turkey, unrelated to the burial place of Aga Khan III.
