I am sorry for giving wrong answer earlier but now i have refered more deeply.

'A)  Both were had polytheistic religions' is common, as both the Mesopotamians and the Ancient Egypt civilization believed in many gods.

EXPLANATION

Mesopotamians were polytheistic; they worshipped several major gods and thousands of minor gods. Each Mesopotamian city, whether Sumerian, Akkadian, Babylonian or Assyrian, had its own patron god or goddess. Each Mesopotamian era or culture had different expressions and interpretations of the godsAncient Egyptian religion was a complex system of polytheistic beliefs and rituals that formed an integral part of ancient Egyptian society. It centered on the Egyptians' interactions with many deities believed to be present in, and in control of the world.

Ancient Egypt was a civilization of ancient North Africa, concentrated along the lower reaches of the Nile River, situated in the place that is now the country Egypt.

'E)  Both enjoyed predictable river flooding that allowed farming.' THIS IS ALSO TRUE!

As Mesopotamians and the ancient Egypt civilizations were both river-based civilizations they did largely depend on the water from the rivers for their crop production. And as they had a lot of water in access, they had probably grown a good amount of crops
