d. the special religious duties a Muslim must observe
d?

Answer 1

D. the special religious duties of a muslim must observe.

Answer 2

One of the Five Pillars of Islam is the prayer - so it's an activity, not a place or an object or people. Because of this already we can reject the first three options: the first one describes a person, the second an object and the third a place.

The correct answer is d). It also inludes giving to charity and a pilgrimage to Mecca.
