Explanation:

• Option a: Groundwater does constitute about 30% of Earth's freshwater, which shows its significance in the overall freshwater storage.
• Option b: In arid or semi - arid regions, surface water sources like rivers and lakes may be scarce or dry up seasonally. Groundwater can be the only reliable source of freshwater for domestic, agricultural, and industrial use in such areas.
• Option c: During droughts, surface water bodies (lakes, rivers) may dry up or have reduced flow. Groundwater, being stored in aquifers underground, can still be accessed through wells, providing a continuous water supply.

Since all of the statements (a, b, and c) are correct reasons why groundwater is an important source of freshwater storage.

Answer:

D. All of the above
