Explanation:
Leguminous plants belong to the family Fabaceae. These plants have a symbiotic association with the soil bacteria called the Rhizobium, that live in their roots, forming root nodules and fix atmospheric nitrogen into the nitrates and nitrites for the plants and in turn, the plants provide the nutrition to the bacteria.
A. Rhizobium is the nitrogen-fixing bacteria living in symbiotic association with leguminous plants.
B. Lactobacillus is used in curdling of the milk.
C. Cyanobacteria are free-living, photosynthetic, nitrogen-fixing bacteria
D. Azotobacter is free-living, nitrogen-fixing bacteria.
Hence, the correct answer is 'Rhizobium
