Answer & Solution

Answer: (Detailed Solution Below)

Option A: Methane

Detailed Solution:

The correct answer is “Methane”.

Compressed Natural Gas (CNG) is mainly composed of Methane. Methane (CH₄) is the primary component of natural gas, typically comprising about 70-90% of its composition. CNG is used as a fuel for vehicles and as a cleaner alternative to other fossil fuels because it produces fewer emissions when burned.

Propane (C₃H₈), Ethane (C₂H₆), and Butane (C₄H₁₀) may also be present in natural gas but in smaller quantities compared to methane.
