Concept:A person who worships other beings is called an idolater.
Explanation:In Islam, worship is due to Allah alone.
Worshipping any other being, such as an idol, god, or goddess, is known as idolatry.
In Islamic teaching, idolatry is called shirk, which means associating partners with Allah.
This practice directly contradicts the principle of Tawhid, which is the absolute oneness of Allah.
Thus, the term used for someone who engages in the worship of other beings is an idolater.
The other options given, such as observer, giver, or believer, do not match this meaning.
An observer is one who watches, a giver is one who provides, and a believer is one who has faith.
Therefore, the most accurate description of a person who worships other beings is an idolater.
Answer:A. Idolater
