Answer: c. Zoroastrianism is monotheistic, but the Vedic religion is polytheistic.
Step-by-step explanation:
Vedism constitutes the basal stone of Hinduism, since historically it is prior to Hinduism. This religion is based on four ancient texts written in Sanskrit called "Vedas" (Veda means "knowledge"), which are Rig Veda, Sama Veda, Yajur Veda and Atharva Veda. In addition, this religion worshiped a trinity of gods (who were later replaced by the trinity of Brahmá, Visnú and Shivá):
-Agni (‘fire’ in Sanskrit), the Vedic god of fire.
-Indra, the king of the gods and lord of Heaven (main God)
-Suri, the sun god.
On the other hand, Zoroastrianism, whose name is due to its founder Zoroaster (Zarathustra Haechataspa) who lived between 660 and 583 BC in ancient Persia (now Iran); bases its philosophy and religion on the mazdeism (based on the teachings of the Iranian prophet and reformer Ahura Mazda whom they recognize as divinity).
That is, for Zoroastrianism, Mazda is considered the only uncreated creator of all.
