C Correct answer
Explanation

Biogas digestion, also called anaerobic digestion, is a process where microorganisms break down biodegradable material (like food waste, agricultural waste, or manure) in the absence of oxygen. This produces methane-rich biogas that can be burned for electricity or heat. While cow methane is captured (not from flatulence directly but from manure management), option C correctly describes the general process.
