The correct answer is - c. pharaoh.
In Ancient Egypt the Pharaoh was the absolute leader of everything, his (occasionally hers) word was law and above everything and that was for both the governing of the empire and the religious life. In fact, the Pharaoh in Ancient Egypt was not considered as a human as everyone else, but as a divine being that is sent from the Gods to rule the empire and has absolute authority in everything in the empire.
