b. to create irrigation systems
c. to divert water from the city of wuhan
d. to relocate 2 million people
my answer is a

I agree.

That is correct! The Three Gorges Dam project in China is primarily an attempt to control flooding. It is one of the largest and most ambitious engineering projects in the world. The dam was built on the Yangtze River to regulate the flow of water, preventing floods in the downstream areas. Flooding has historically been a major problem in the region, causing extensive damage and loss of life. The construction of the dam helps to mitigate these risks by holding back water during peak flood periods and then gradually releasing it.
