The correct answer is: A) Chera Dynasty
Pathitrupathu is a collection of 100 poems written in Tamil by the ancient Tamil Sangam poets. The poems are about the life and times of the Chera kings, and provide valuable insights into the history and culture of the Chera dynasty.
The Maurya Empire was an ancient Indian empire that ruled over much of the Indian subcontinent from the 4th century BCE to the 2nd century BCE. The Pandya kingdom was an ancient Indian kingdom that ruled over much of the southern Indian peninsula from the 3rd century BCE to the 13th century CE. The Chola dynasty was an ancient Indian dynasty that ruled over much of southern India from the 9th century CE to the 13th century CE.
Pathitrupathu is not a work of literature that gives insights into any of these other dynasties.
