Each of the options listed (a, b, c, and d) accurately describes a function of soil for crop production:
- a) Soil gives physical support to plants: True, soil provides the necessary anchorage.
- b) Soil supplies and stores water: True, soil acts as a reservoir for water needed by plants.
- c) Soil supplies mineral nutrients: True, soil contains minerals that are essential for plant growth.
- d) Supplies air to roots: True, soil allows for the exchange of gases, which is necessary for root respiration.
Since all the options are true, "All of the above" (e) is not true if interpreted as something that does not describe a function of soil. Therefore, the answer is e) All of the above.
