Available water for plant indicates water held in

Correct option is A

Available water is the portion of soil water that plants can absorb and utilize. It is held in the soil between field capacity (~0.33 bar) and permanent wilting point (~15 bar). Below field capacity (0.33 bar), water drains quickly due to gravity (gravitational water), and above 15 bar, water is held too tightly by soil particles for plants to extract (hygroscopic water).
