Explanation:

Jama Masjid, Delhi (Correct): The Jama Masjid in Delhi was commissioned by Mughal Emperor Shah Jahan, Akbar's grandson, and was completed in 1656. Shah Jahan's reign was from 1628 to 1658, whereas Akbar's reign was from 1556 to 1605. Therefore, the Jama Masjid was not built during Akbar's reign. Agra Fort: Its construction was initiated by Emperor Akbar in 1565 and completed in 1573, falling within his reign. Fatehpur Sikri: This city was founded as the capital by Emperor Akbar in 1569, and its various buildings were constructed during his reign (1571-1585). Buland Darwaza: Located at Fatehpur Sikri, it was built by Akbar in 1601 to commemorate his victory over Gujarat, also within his reign.
