The correct answer is option 3: Pandyas. The Pandyas were the patrons of Sanga-ma Literature. Sanga-ma Literature refers to a collection of Tamil literature that was created during the Sangam period in ancient Southern India. The Pandyas were one of the three major Tamil dynasties during this period, with the other two being the Cholas and the Cheras. They were known for their strong support and patronage of the arts, literature, and poetry. Some of the most famous works of Sanga-ma Literature, such as the Tolkappiyam and the Eight Anthologies, were created under their patronage. It is important to note that while the Nayakas, Chandellas, and Solankis were also powerful dynasties in different parts of India, they were not associated with the patronage of Sanga-ma Literature.
