(d) I, II and III

Marsh gas, sometimes known as methane, is created underwater by anaerobic bacterial decomposition of plant materials in the rumen of herbivorous animals.

Methane, a molecule having one carbon atom and four hydrogen atoms, is the most abundant component of natural gas (CH₄).

About 55-65 percent of raw biogas is methane (CH₄), 30-45 percent is carbon dioxide (CO₂), with traces of hydrogen sulphide (H₂S) and a small amount of water vapour.
