Answer:
B. Islam
Explanation:
Roughly 97% of Pakistanis are Muslim. Inside Islam, similar to the Christian confidence, there is a division between belief system/religious philosophy. Some stick to the Sunni Islam confidence, which I accept is overwhelmingly the confidence of most Muslims living in Arab nations and the other being, Shia. You catch wind of Sunnis and Shias warring with one another. From what I hear, there is a contrast between these two religions.
