Correct option is B
The correct answer is (B) Prabhakaravardhana
Prabhakaravardhana is considered the first notable king of the Pushyabhuti dynasty, ruling approximately between 580–605 CE.
He established the political prominence of the dynasty and extended its influence in Thanesar (modern-day Haryana) and nearby regions.
Prabhakaravardhana successfully defended his kingdom against the Huna invasions and played a crucial role in laying the foundation for his son Harshavardhana’s later empire.
He bore the title of Maharajadhiraja, showing his imperial ambitions and growing authority.
The Pushyabhuti dynasty ruled mainly in Northern India, with its capital at Thanesar.
Prabhakaravardhana had three children: Rajyavardhana, Harshavardhana, and Rajyashri.
His son Rajyavardhana succeeded him but ruled briefly before being killed by Shashanka of Gauda.
Harshavardhana (Harsha) took over in 606 CE, eventually creating a vast empire extending from Punjab to Bengal.
The main source of Harsha’s reign is Harshacharita, written by Banabhatta, and accounts of Xuanzang (Hiuen Tsang).
Option A (Rajyavardhana): He was Prabhakaravardhana’s elder son and briefly ruled after him but was not as politically significant or long-lasting in impact.
Option C (Harshavardhana): The most famous ruler of the dynasty but not the first notable king—he expanded the kingdom built by his father.
Option D (Naravardhana): Considered the founder of the Pushyabhuti dynasty, but he did not attain political significance or notable achievements like Prabhakaravardhana.
The rise of the Pushyabhuti dynasty occurred during the post-Gupta period, a time of regional kingdoms emerging after the decline of Gupta power.
