Which of the statements given above are correct?

345065 Assertion :
Compressed natural gas \((\mathrm{CNG})\) is natural gas under pressure and mainly composed of methane.
Reason :
One of the advantages of using \(\mathrm{CNG}\) as a fuel in automobiles is that it requires very less space for storage as compared to that of petrol or diesel.
