Solution
The correct option is D Rhizobium
The bacterium rhizobium can fix atmospheric nitrogen in the soil. But rhizobium cannot make it's own food. Therefore, it exists in the root of leguminous plants like gram, peas and other legumes. They provide nitrogen to the plants, and in return plants provide them with shelter and nutrients.
