Correct Answer: (d) 1 and 4 are correct.
Note: In Vedas, Indra is the King and the Dev of Svarga (Heaven). He is the God of heaven, lightning, thunder and rains. Guardian of the Moral order (Rit) was lord Varuna. Some hymns, are prayers to God Indra for punishing the sinners, but in the absence of option 1, 2 and 4 we choose 1 and 4.
