Which of the following biofertilizers is correctly matched with its ecological nature and its broad taxonomic group?

Step-by-step solution

Glomus is a genus of fungi that forms a symbiotic association with plant roots (mycorrhiza) to function as a biofertilizer, primarily absorbing phosphorus from the soil. Rhizobium is a symbiotic bacterium, not free-living, that forms root nodules in leguminous plants. Azotobacter is a free-living nitrogen-fixing bacterium, not symbiotic. Therefore, only Glomus is correctly matched as a symbiotic fungus. Answer: Glomus - Symbiotic - Fungus
