Solution

The correct option is C Assertion is correct but Reason is incorrect
Assertion:
Plants absorb water mostly by roots.
Reason:
Root cap region participates actively in water absorption.
Assertion is correct but Reason is incorrect.

Plants have the potential to absorb water through their entire surface right from root, stem, leaves, flowers, etc. However, as water is available mostly in the soil, only the underground root system is specialized to absorb water. In roots, the most efficient region of water absorption is the root hair zone.
