Answer:
The correct option is D. In a typical stream, where the gradient is steep, the discharge is small.
Step-by-step explanation:
A stream can be described as a channel in which water flows. The surface of the stream in water flows in beds across a channel. If a stream of water is large enough, it is termed as a river. Typically, a stream begins with steep gradients sometimes called as a young steep.
If the gradient of a stream is steep, then less water will discharge from the gradient steep.
