Where did Bismillah Khan play the shehnai on Independence Day?

Correct answer: Red Fort

The historical detail in the lesson is that Ustad Bismillah Khan played the shehnai from the Red Fort in Delhi on 15 August 1947, when India became independent. Therefore, option A is correct. The location is significant because the performance connected his music with a major national celebration and helped establish the shehnai as an instrument of public cultural importance. India Gate, Qutub Minar and Rashtrapati Bhavan are important places in Delhi, so they may appear plausible, but none is the venue named for this Independence Day performance. Remembering the paired clues—Bismillah Khan, Red Fort and 15 August 1947—leads to the answer.
