Answer
(c) I and III
Work Step by Step
I. increasing runoff
III. increasing percolation
The hydrologic cycle has to do with water's movement around the biosphere. Evapotranspiration (combination of evaporation and transpiration) is greatly present in this cycle. Human activity can reduce evapotranspiration. If this is reduced, then there will be more water left in the soil and/or on the ground, leading to an increase of runoff and percolation.
