Answer:
D Christianity
Step-by-step explanation:
The Maurya Empire was the first unified great empire of India. Ruled by the Maurya dynasty, it lasted from 320 a. C. to 185 a. C. (probable dates), dominating all the north and center of India and some regions of Afghanistan and Pakistan.
Taking into account the dates in which the empire was developed, we can say that the Christianity did not exist yet, and therefore it is impossible that it was practiced.
