Answer:
D) all are majority Islamic countries
Step-by-step explanation:
In the map linked to this answer, Indonesia, Jordan, Saudi Arabia, and Turkey are all colored green, which indicates their population's main religion is Islam. Alternatively, you could view the religions of these countries via the CIA's World Factbook. The statistics on the site claim that Indonesia has 87.2% Muslims, Jordan has 97.1% Muslims, Saudi Arabia has 85-90% Sunni Muslims & 10-12% Shia Muslims, and Turkey has 99.8% Muslims. This clearly proves that these four countries are primarily Islamic countries; therefore, option D is correct.
Note: Muslim is the name given to someone following Islam (similar to Christians being people that follow Christianity). Shia and Sunni are terms used to describe different types of Muslims depending on the branch they follow.
