The Ain-e-Akbari, compiled by Abul Fazl, is one of the most important sources for understanding the agrarian history of the Mughal Empire, particularly during the reign of Akbar in the late 16th century. It forms part of the larger work called Akbarnama.
The Ain-e-Akbari provides detailed statistical and administrative records related to the empire’s economy, including land revenue systems, agricultural productivity, classification of land, crop types, prices, and information about peasants and zamindars.
While options (A), (B), and (D) are related to agrarian history, they are more general in nature. It is the Ain-e-Akbari that compiles all such aspects systematically, making it the most comprehensive primary source on the subject.
Hence, Option (C) is the correct answer.
