The statement that best describes the beliefs of Zoroastrianism is:
- Good and evil constantly struggle for control of the universe.
Zoroastrianism revolves around the duality of good and evil, represented by Ahura Mazda (the supreme god) and Angra Mainyu (the evil spirit). The belief in the ongoing struggle between these forces is central to the religion, and humans play an active role in this struggle by making choices that align with good or evil.
The other statements do not accurately reflect Zoroastrian beliefs.
