What was the goal of Hijra?

A. to conquer the city of Mecca

B. to open up a trade route to the west

C. to get enough water to survive

D. to escape persecution

I'm not asking for the answer its self but more of either how to find the answer or the answer and how you could find it. I'm really struggling with this question.

The correct option is C

The jisras come to celebrate the birth with songs, blessings and omens of long life and prosperity, as well as to free it from the evil eye. In return they receive rice, sugar and money. If the jisras consider that they receive little amount of alms, they can curse the child with being an impotent man.

The right answer is D. to escape persecution
