Correct answer
A. (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
Step-by-step solution
Mycoplasma are organisms that completely lack a cell wall. Methanogens are present in the gut of several ruminant animals and are responsible for the production of methane (biogas) from the dung of these animals. Chemosynthetic autotrophic bacteria oxidise inorganic substances and play a great role in recycling nutrients like nitrogen, phosphorous, iron and sulphur. Cyanobacteria often have specialised cells called heterocysts for nitrogen fixation. Therefore, the correct matching is (A)-(IV), (B)-(III), (C)-(I), (
