Reason: It is a clean burning fuel which causes less pollution. Also it has higher ignition temperature and it is a non-toxic fuel that does not pose any danger of contamination to the ground water.
A. Both assertion and reason are correct and reason is the correct explanation for assertion.
B. Both assertion and reason are correct but reason is not the correct explanation for assertion
C. Assertion is correct but reason is incorrect
D. Both assertion and reason are incorrect

Answer 1

Hint: CNG is compressed natural gas which is a better and eco friendly alternative to usage of petrol and gasoline. It is the fuel for the future. It is safer and non toxic to the surroundings. It had higher ignition temperature. It is a renewable gas.

Complete step by step answer:
We know that with the increasing population and human demands it is becoming very difficult to survive on the available resources and thus, to meet all our needs we need an alternative resource for meeting our needs.
CNG is the compressed natural gas, as the name suggests it compresses natural gas to a volume of 1%. It is an eco-friendly alternative to all our demands. It is the best alternative to petrol and gasoline and causes no pollution and is non toxic to ground water and other surroundings. It is renewable as it is easier to obtain natural gas as compared to others which are derived from fossil fuels. CNG is cleaner than coal or any other gas we use.
It is a clear, non-corrosive and colourless gas which has very little carbon emissions, It is stored under high pressure. It is cheaper and a greener alternative to all our needs. CNG is usually not used at homes because household stoves require less pressure and therefore, gas cylinders are provided with regulators. CNG is used in automobiles. Thus, for a better future it is important to switch to those alternatives that are less toxic to the present as well as the future. It is lighter than air.
CNG is a better fuel than petrol. It is a clean burning fuel which causes less pollution. Also it has higher ignition temperature and it is a non-toxic fuel that does not pose any danger of contamination to the ground water.
Thus, we know that the answer to the above question is option (A)
Both assertion and reason are correct and reason is the correct explanation for assertion.

So, the correct answer is Option A.

Note: Natural gas constitutes various proportions of different elements that together make natural gas. Methane is a very important component of natural gas and combustion of natural gas is carried out as:
$CH_4+2O_2\to CO_2 +H_20$
