Correct answer: A
Explanation
Amir Khusro (1253-1325) belonged to the Delhi Sultanate era, Tansen (c.1500-1586) was a court musician of Akbar, and Thyagaraja (1767-1847) was a Carnatic composer of the 18th-19th century. The correct time order is therefore Amir Khusro, then Tansen, then Thyagaraja, matching 1-2-3.
