AMethane ✓ Correct
BButane
CEthane
DPropane
Correct answer: (A) Methane
Explanation
The main constituent of compressed natural gas is methane.
Butane is a major part of LPG, not of CNG.
Ethane occurs only in small amounts in natural gas.
Propane too is a minor component, not the main one.
Being mostly methane, CNG burns cleanly with little particulate output.
It is stored at high pressure to pack enough fuel into a vehicle tank.
