Which among the following is major component of Gobar Gas?

Methane

The correct answer is Option (4) → Methane

Gobar Gas (also known as biogas) is produced by the anaerobic decomposition of organic matter such as cow dung (gobar), kitchen waste, and agricultural residues. Its major component is Methane (CH₄), which typically constitutes 50-75% of the gas mixture. Other components include carbon dioxide (CO₂), and smaller amounts of nitrogen (N₂), hydrogen (H₂), and hydrogen sulfide (H₂S).

Butane, Ethane, and Propane are hydrocarbons found in liquefied petroleum gas (LPG), not in biogas as major components.
