Question

what is an ayatollah?
a religious leader of iran
a person or group following a strict set of principles
the term for a king of iran
the act of doing what is required

Explanation:

An ayatollah is a high - ranking religious leader in Shia Islam, particularly in Iran. The second option describes a person with strict principles (too general), the third is incorrect as the term for a king of Iran is not ayatollah, and the fourth is about fulfilling requirements (not related). So the correct option is the one about a religious leader of Iran.

Answer:

A. a religious leader of Iran
