In which of the following agricultural setups, the nutrient needs of one crop are fulfilled by the other crop?


A
B

here,groundnut soyabeans and wheat all are legumes which have nodules at their roots for rhizobium bacteria, which fixes atmospheric N2 --->nitrates.so, only rice crop's requiremnts need to be fulffilled by any of the other crops.So,the correct diagram must show rice and any one other crop(because the question reads "other crop" not crops)So ideally,D should be the correct option. How is C right boggles me.
