Which of the following is an example of a monotheistic religion?

Islam is an example of a monotheistic religion because it emphasizes the belief in a single, all-powerful God, referred to as Allah in Arabic. This is a foundational aspect of the Islamic faith, which distinguishes it from polytheistic belief systems that worship multiple deities. In Islam, the concept of monotheism is deeply rooted in the teachings of the Quran and the practices of the Prophet Muhammad, who is considered the final prophet in a long line of messengers conveying God's will.

Buddhism, while it has many followers and rich traditions, does not focus on the worship of a god or gods in the same way that monotheistic religions do; rather, it is considered more of a philosophy or spiritual practice. Polytheism is, by definition, the belief in multiple gods, which directly contradicts the principles of monotheism. Agnosticism is a philosophical position regarding the existence of God, suggesting that the existence or non-existence of a deity is unknown or unknowable, and does not establish a belief in one singular God.
