(b) CH₄
Explanation:
- Marsh gas is also known as bio gas which is formed by the decay and decomposition of the living material like plants and herbivore animals.
- In the presence of water or wet lands, the anaerobic bacteria feed on these material for their survival and produce gases like methane, hydrogen sulfide and the carbon dioxide.
- Since methane is present in the highest amount ranging from 60-80 percent in marsh gas therefore marsh gas is also known as methane gas.
- The marsh gas is odourless and can be flames easily.
- Thus, Option-B is the correct answer.
