Assertion : Methanogens are present in the gut of several ruminant animals.

Options

B. If both assertion and reason and true and reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.

Answer

B

Explanation

Methanogens occur in marshy areas where they converts formic acid and carbon dioxide into methane with the help of hydrogen. Some of hte methanogen archaebacteria live as symbionts (e.g. Methanobacterium) inside rumen or first chamber in the stomach of herbivorous animals that chew their cud (ruminants, e.g. cow, buffalo) and they help in production of methane from dung of these animals. These archaebacteria are helpful to the ruminants in fermentation of cellulose.
