Concept:Rainwater that enters the soil after heavy rain is grouped by how it moves or remains within the soil layers.
Explanation:When heavy rainfall occurs, the soil pores become completely saturated with water.
The excess water drains downward through the large pores under the influence of gravity.
This freely draining portion is called gravitational water.
Once gravitational water has fully drained away, the soil still holds some moisture within its smaller pores and around soil particles.
The water that remains in the soil after excess water has been removed by drainage is known as field capacity.
Field capacity is the maximum amount of water that a well-drained soil can hold against the force of gravity.
At this stage, capillary water occupies the tiny pores and is readily available for absorption by plant roots.
Gravitational water is the portion lost to drainage, while hygroscopic water forms a very thin film tightly bound to soil particles and is generally unavailable to plants.
Therefore, the soil water that persists after gravitational water has drained off is field capacity water.
Answer:Field capacity (Option A).
