Solution

The correct option is C A: Denitrification, B: Ammonification
In the given diagram (A) represents denitrification and (B) represents ammonification.
Denitrification is the conversion of nitrates into nitrogen gas by some microorganisms e.g. Pseudomonas denitrificans, Thiobacillus denitrificans, Micrococcus denitrificans.
Ammonification is the conversion of dead remains of living organisms into ammonia with the help of microorganisms like Bacillus ramosus, B. vulgaris, B. mesentericus, etc.
So, the correct answer is option C.
