Solution

The correct option is B Chresard = hollard - echard
Plants require water for the metabolic actions which is absorbed by the roots of the plants. The total water which is poured in the soil is not available to the plants.bThe total water content present in the soil is called hollard. Chresard is 75% of capillary water, water actually available for plants so that they can absorbed for their growth. Echard is remaining water. Therefore, correct relationship between them is Chresard + Echard = Hollard or Chresard = Hollard - echard. Thus, the correct answer is option B.
