(D) Organic fertilizers or biofertilizers are organisms that enrich the nutrient quality of the soil. $1$. Bacteria (e.g.,$Rhizobium$,$Azospirillum$) fix atmospheric nitrogen. $2$. Cyanobacteria (e.g.,$Anabaena$,$Nostoc$) are autotrophic microbes widely used in paddy fields to fix nitrogen and add organic matter. $3$. Fungi (e.g.,$Mycorrhiza$) form symbiotic associations with roots to help in phosphorus absorption. Since all these groups are used as biofertilizers,the correct answer is $D$.
