Answer: Option B

Field capacity is the maximum limit of the water available in the soil, after the drainage of excess water. The physical definition of field capacity is the bulk water content retained in the soil at $$-$$33 kPa of the hydraulic head or suction pressure.
Thus in field capacity, the water is held at a tension of $$-\frac{1}{3}$$ bar.
