C. 50% of the area is vegetation and 50% is roofed or paved

D. All of the above will have the same runoff

Answer 1

The answer is B because there is less vegetation to stop the water from running off

Answer 2

Answer: The correct option is B. 25% of the area is vegetation and 75% is roofed or paved.

Vegetation can cause precipitation and reduce runoff. Leaves and stems are used in capturing rain and prevents the rainwater to reach the ground. Dense vegetation with higher surface area under vegetation absorbs water and prevents runoff. Pavements or roofs cause the runoff water by filling the waterways as there is no vegetation for water absorption which leads to overfilled waterways and in turn cause flooding.
