Select the correct answer. In which of these ways is Islam similar to both Christianity and Judaism? A. All three religions worship Allah as the supreme god. B. All three religions believe in the concept of the Messiah. C. All three religions were founded in the Middle East. D. All three religions support the idea of reincarnation.

The correct answer is C. All three religions were founded in the Middle East.

Explanation:
- A is incorrect because while Christians refer to God as "God" (and may use other names), Muslims specifically worship "Allah," which is the Arabic word for God.
- B is also incorrect because the concept of the Messiah is understood differently in each religion. Christianity has a specific belief in Jesus as the Messiah, while Judaism and Islam have different views.
- D is incorrect as none of these religions subscribe to the idea of reincarnation; instead, they have different beliefs about the afterlife.
