Answer:

Optiion C.

The lowest point in which a stream can erode it's channel

Explanation:

Base level is the lowest level in which a stream can erode it's channel.

The stream of water stop flowing when it reaches it's base level. The stream of water cannot cut deeper into it's base so it's cut into banks side ways. The stream then meanders and widen it's valley as a result of cutting into it's banks
