Which of the following describes a major difference between early Persian and Greek religion?

Persian - Zoroastrianism

Greek - Polytheistic

Zoroastrianism affected the way the Persians governed their subjects by allowing the territories under their rule to worship their own religion. Many of the Persian Monarchs like Cyrus the Great were deeply devoted to Zoroastrianism and never imposed it on the places that they have conquered. They were very tolerant about other people’s faiths. This tolerance and kindness had a deep effect on other religions.
