Correct option is (d) Grams and pulses

To explain I would say: Grams and pulses are leguminous plants which increase the fertility of the soil by fixing environmental nitrogen with the help of Rhizobium bacteria. This helps reducing crop diseases and wastage due to insects and hence increases overall crop yield.
