Correct option is B
The Vishnu Purana is one of the major Puranas, which covers cosmology, genealogy of kings, mythology, and legends. However, it is not particularly noted for its account of the Mauryan dynasty. Historical accounts of the Mauryans are mainly derived from sources like Megasthenes' Indica and Ashokan inscriptions.
The Matsya Purana, on the other hand, is regarded as more reliable for the history of the Andhra region, particularly for the Satavahanas (Andhra dynasty). It provides genealogical records and other important historical details concerning the Andhra region. Therefore, while the Vishnu Purana has value in other contexts, the Matsya Purana is considered more relevant for Andhra's historical study.
