Answer:
D. Taxes
Step-by-step explanation:
The economy in ancient Egypt was based on agriculture. The Nile River, with its floods, was a godsend to the Egyptians. The cultivated land belonged to Pharaoh, considered by his people king, God, and absolute master, but was controlled by the priests, scribes, and military chiefs who administered the free farmers and the slaves who cultivated the land.
One of the characteristics of the Egyptian economy was the centralizing power of the state in the figure of Pharaoh. At the Emperor's request, craftsmen were required to build temples and manufacture weapons for the army.
The taxes were so heavy that many people went into debt, and during the late period of ancient Egypt (about 525-332 BC) people sold themselves on duty, offering their time and work to pay their taxes.
