Solution
The correct option is D Rhizobium
- Rhizobium is nitrogen-fixing bacteria for leguminous crops (like soybean, groundnut, mung, chickpea, all types of beans, methi, alfalfa) in association with the roots of leguminous plants in the form of root nodules.
- These microorganisms fix the atmospheric nitrogen in the roots and make it available to plants, which plants cannot fix directly and makes the soil fertile and also increases the plant health.
- Whereas Nostoc, Azotobactor, and Azospirilum are the nitrogen-fixing bacteria for crops like tea, coffee, rice, etc.
