Explanation:

- According to the Shariat (Islamic law), if one of the parents is a Muslim, the child is automatically considered a Muslim.

- Option 1: Belonging to the religion mutually agreed by the parents

- This is not accurate, as Shariat does not make a child's religion subject to parental agreement if one is Muslim.

- Option 2: Belonging to the religion of the father

- This is not entirely correct, as the law prioritizes Islam if either parent is Muslim.

- Option 3: Belonging to the religion of the mother

- Also incorrect; the child is considered Muslim if either parent is Muslim.

- Option 4: None of the above

- This is incorrect, because the correct answer should state that the child is Muslim if either parent is Muslim.

Correct Answer: Option 2 (Belonging to the religion of the father), is most often accepted, as traditionally, the religion of the father is usually taken if both parents are of different faiths, but if any one is a Muslim, the child is considered a Muslim by Shariat.
