Concept:Soil water is normally classified into gravitational, capillary, and hygroscopic water. Only one type remains after free drainage.
Explanation:Heavy rainfall pours excess water into the soil.
Gravitational water drains downward under the force of gravity.
After this excess water has drained off, the soil still holds water in its fine pores and around soil particles.
This remaining water is known as capillary water.
It is held by surface tension and is the main water available to plants.
Field capacity is merely the moisture condition of the soil after drainage, not a type of water.
Hygroscopic water is tightly bound and is not the water left after quick drainage.
Thus, the water left in the soil after excess water has drained is capillary water.
Answer:B. Capillary water
