Answer:
A.
Step-by-step explanation:
If we were to go with B, then it would exclude others from different cultures, doing what he is trying to.
If we went with C, then they wouldn't get along very well, because no one likes to be forced into a different religion.
If we went with D, he wants an appreciation, so training some people to change religions if there are complaints, is not going to cut it. Therefore, we have A. Which I do not need to explain.
