How does the vegetation surface type affect the amount of runoff

The type of vegetation a surface does affect the water coming from above to sink in or runoff.

Explanation:

This is how the vegetation affects the runoff:-

The leaves and stems present in the vegetation do not let the water fall directly on the soil and makes the process rather slow which makes the water to get to the ground slowly and sink in properly inside the soil rather than running off.

If the vegetation present is dense with  there was being hairy then also the water would not run out and will get absorbed by the roots letting the soil intact

i think   the answer is c hope i'm right
