The correct answer is: D: WAHHABIS are a branch of the Shia, Muslim.
Wahhabism is actually a strict and conservative branch within Sunni Islam, not Shia Islam. Wahhabi teachings originated in the Arabian Peninsula in the 18th century and have become influential in Saudi Arabia and other parts of the Sunni Muslim world. They adhere to a literal interpretation of the Quran and reject any modern interpretations or adaptations of Islamic teachings. While they may have some differences with other Sunni Muslims in southwest Asia, such as their strict interpretation of Islamic law, they still consider themselves part of the Sunni branch of Islam.
