Which of the following God was the most prominent in Rig Veda?

Indra

The correct answer is Option 2- Indra

The most prominent god in the Rig Veda is Indra.

Indra is the god of rain and thunder, and is also associated with war and battle. He is often depicted as a mighty warrior riding on a white elephant named Airavata.

In the Rig Veda, Indra is praised for his many victories over the asuras, the enemies of the gods. He is also credited with slaying the dragon Vritra, who was holding back the rains and causing a drought. Indra's victory over Vritra is seen as a symbol of his power and his ability to protect the people from harm.

Indra was a very popular deity in the early Vedic period, and his worship was widespread. He was invoked in hymns and prayers for victory in battle, for rain, and for protection from harm.

The other gods that are mentioned are also important deities in the Vedic pantheon, but they are not specifically associated with war. Surya is the sun god, and Shiva is a later deity who is not mentioned in the Rig Veda. Vishnu is mentioned in the Rig Veda, but he is not as prominent as Indra.
