Ancient Indian literature includes vast treatises on various subjects. The most foundational text for all Indian classical performing arts (music, dance, and drama) is the Natyashastra.
Step 1: Matching the Text to the Author.
The Natyashastra is traditionally attributed to the sage Bharat Muni. It is often referred to as the "Fifth Veda" because of its immense cultural and religious significance.
Step 2: Clarifying other options.
• Sarangdev: Author of *Sangita Ratnakara* (13th century).
• Abhinavgupt: Wrote the *Abhinavabharati*, the most famous commentary on Bharat's Natyashastra.
