• B. Absence Of Carbon
• C. Presence Of Carbon
• D. Presence Of Oxygen

Answer 1

The correct option is A

Absence Of Oxygen

The correct option is A.

Explanation of the correct option:

1. The amalgamation of different gases along with methane is generated by the action of microbes in the biogas.
2. It is primarily used as fuel, and the microbes that work to produce the biogas are known as the methanogen bacteria.
3. The methanogen bacteria or methanogens are obligate anaerobic bacteria, thus, they do not possess to survive in the presence of oxygen or aerobic conditions.
4. These bacteria develop anaerobically on cellulose and generate huge concentrations of methane gas along with carbon dioxide and hydrogen.
5. These bacteria are generally found in the anaerobic sludge tanks of sewage treatment plants.
6. Apart from this, methanogen bacteria are also found in the cattle’s rumen, thus, they are also found in their excretion, that is, gobar. This gobar also helps in the generation of biogas or gobar gas.

Final answer: Absence of oxygen is required during the production of biogas.
