A
Lower drainage density results in higher peak in flood hydrograph compared to that when the drainage density is higher.
B
Lower drainage density results in lower peak in flood hydrograph compared to that when the drainage density is higher.
C
Lower drainage density results in a flood hydrograph with a longer time base compared to that when the drainage density is higher.
D
Lower drainage density results in a flood hydrograph with a shorter time base compared to that when the drainage density is higher.

Correct : c
