(D) Biofertilizers are organisms that enrich the nutrient quality of the soil. $Rhizobium$, $Nostoc$, and $Mycorrhiza$ are well-known biofertilizers. $Rhizobium$ is a symbiotic nitrogen-fixing bacterium, $Nostoc$ is a cyanobacterium that fixes atmospheric nitrogen, and $Mycorrhiza$ is a symbiotic association between fungi and plant roots that helps in phosphorus absorption. $Agrobacterium$ (specifically $Agrobacterium$ $	ext{tumefaciens}$) is a soil bacterium used in genetic engineering as a vector for gene transfer, but it is not classified as a biofertilizer.
