The answer is a. They constructed the Aswan Dam to eliminate seasonal flooding.

The Aswan Dam or Aswan High Dam was built from 1898-1902. It was primarily built to control the floods in the nearby areas of the river. Consequently, the dam also became useful for providing water for farmers and generating hydroelectricity. The dam releases around 55 km^3 of water a year, 46 km^3 of which are used for irrigation.
