Answer:
Hello there! Elizabeth here! I would choose either B:the Mediterranean Sea & D:Nile River. But if your answer only required 1 answer, then I would 100% choose C. Nile River, or else wise the Egypt civilization wouldn't be able to server their 'Boss', or to be able to survive by not eating the wheat bread.
