Groundwater flows from .
a. valleys to hills high
b. to low-pressure areas
c. valleys to drainage divides
d. low to high-pressure areas
e. discharge to recharge

Option (B)

Explanation:

Groundwater refers to the subsurface flow of water, from a region of higher pressure to a region of lower pressure. The water always moves from high elevated region to a low elevated region. The quantity of groundwater increases when more amount of water is added into it through the area of recharge and also decreases when the amount of water eliminated through the area of discharge.

Thus, groundwater covers some part of the freshwater region of earth.

Hence, the correct answer is option (B).
