Which dynasty did ruled over Magadha after the Nanda Dynasty?

Explanation

The Nanda dynasty in Magadha was established after ending the Shishunaga dynasty. There were a total of 9 kings in the Nanda dynasty. In the later period of the Nandas, the people turned against the rulers due to forcible collection of money and heavy taxes even on small items, and an atmosphere of hatred and discontent spread everywhere. Taking advantage of this situation, Chandragupta Maurya, with the help of Chanakya, killed Dhanananda and ended the Nanda dynasty. Thus, immediately after the Nandas, the Maurya dynasty was established in Magadha. After that, the Shungas, Kanvas, Guptas, etc. ruled. Therefore, as per the question, the nearest correct answer is option (a).
