Correct Answer: (a) Polytheistic
Note: The most interesting aspect of Rig Vedic religion was its polytheistic character in which a number of Gods were worshipped. The Rig Vedic Aryans worshipped nature with intense feeling and endowed it with animated soul. Vedic Gods were mainly classified into three groups- (1) God of sky-Varuna, Mitra, Surya, Vishnu, etc. (2) God of space- Indra, Rudra, etc. (3) God of the earth- Agni, Brihaspati, Soma, etc. Whenever these Vedic saints worship any God, they consider him to be the Supreme God, this is known as Ekaikyavaad. Other than this in Rigveda Ekeshwarvaad is supported by saying Ekm Satt vipra bahudha badanti". Ekeshwarvaad of Rigveda included vision of Advaityavaad, Sarvadevtavaad and Bahudevatavaad. But the concept of one supreme God of Vedas is different form the modern Ishwarvaad.
