The first Gupta ruler to assume the title of `Parama Bhagawat’ was

Chandragupta I
Samudragupta
Chandragupta II
Ramgupta

The correct answer is (c) Chandragupta II.

Chandragupta II was the third ruler of the Gupta Empire, who ruled from 375 to 415 CE. He is also known as Vikramaditya, which means “sun of power”. Chandragupta II was a great conqueror and expanded the Gupta Empire to its greatest extent. He is also known for his patronage of art and literature.

The title “Parama Bhagavat” means “supreme devotee of Vishnu”. It is a title that is given to Hindus who are particularly devoted to Vishnu. Chandragupta II was a devout Hindu and is said to have been a great devotee of Vishnu. He is said to have built many temples dedicated to Vishnu and to have performed many religious rituals.

The other options are incorrect. Chandragupta I was the founder of the Gupta Empire and ruled from 320 to 335 CE. Samudragupta was the second ruler of the Gupta Empire and ruled from 335 to 375 CE. Ramgupta was the fourth ruler of the Gupta Empire and ruled for a short period of time in 415 CE.
