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.
<em>I hope this helped you! I'm so sorry if my answer is incorrect!</em>
While all are essentially important to the civilization of Egypt, ancient civilizations such as Egypt were dependent on heavy natural resources, especially considering how economically undeveloped they were. The Nile river was their main water source and they were sure to build most of their civilization near it, so all in all, the Nile River was the most influential to the development of ancient Egyptian Society.
