In which language was the Sangam literature of South India, composed between 300 BCE and 300 CE, primarily written?

The correct option is Tamil.

Explanation:

Sangam literature refers to the ancient Tamil literature produced during the Sangam period, spanning roughly from 300 BCE to 300 CE in South India.

The term 'Sangam' refers to an assembly or academy of Tamil poets and scholars that functioned under the patronage of the Pandyan kings in Madurai. The works compiled during these assemblies represent the earliest known body of literature in South India and were composed primarily in the early Tamil language.

Key collections of Sangam literature include the Ettuthokai (Eight Anthologies) and the Pattupattu (Ten Idylls), which provide invaluable insights into the social, economic, cultural, and political life of ancient South India.
