The river overflowed its …… and flooded the area. A. edges B. fronts C. limits D. banks

The correct answer is D. banks.

A river’s banks are the land that borders the river on either side. When a river overflows its banks, it floods the area beyond the banks. This can cause extensive damage to property and infrastructure, and can also lead to loss of life.

The other options are incorrect because they do not refer to the land that borders a river. Edges are the outer limits of something, fronts are the parts of something that face forward, and limits are the boundaries of something.
