The Egyptians worshiped multiple gods. The Hebrews worshiped one God. The Egyptians were plagued by the Hebrew God, and eventually, the God of the Hebrews got them out of Egypt. I would say both, because the Hebrew people definitely recognized the power of God, and the Egyptians pleaded with Pharaoh to just give in and let the Hebrews go, but he was stubborn.
Based on this I would say:
C. Both
