1- Bimbisara
2- Ajatasattu
3- Mahapadma Nanda
4- Chandragupta Maurya

Choose the correct answer from the given options:

None of the above

Early Buddhist and Jaina writers, however, attributed Magadha's ascendancy to the policies pursued by ambitious kings such as Bimbisara, Ajatasattu, and Mahapadma Nanda, along with the support of their ministers, who played a vital role in implementing these policies.

Chandragupta Maurya was the founder of the Mauryan empire which was in the Magadha region, present day Bihar.  Accession of Chandragupta Maurya took place around 321 BCE.
