Question

Primary fuel among the following is

• A. Petrol
• B. Natural gas
• C. Diesel
• D. Kerosene

Answer 1

The correct option is B

Natural gas

Explanation of correct option.

Option (B ) is correct.

• Natural gas is a hydrocarbon mixture consisting primarily of saturated light paraffin such as methane and ethane, both of which are gaseous under atmospheric conditions.
• Natural gas is obtained directly from nature and therefore it is considered a primary fuel.

Explanation of incorrect options:

Option (A) Petrol

• Petrol is the liquid that is used as fuel for vehicles such as cars and motorbikes.
• Petrol is a fossil fuel that is made by millions of years of decomposition of dead plants and animals inside the oceans.
• Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
• Hence, incorrect option.

Option (C) Diesel

• Diesel fuels and other petroleum products are earlier manufactured by refining crude oil.
• They can be also produced synthetically from various carbon-bearing feedstocks.
• A common feedstock is natural gas, but synthetic fuels can be also produced from such sources as coal or biomass.
• Hence, incorrect option.

Option (D) Kerosene

• While kerosene can be extracted from coal, oil shale, and wood.
• It is derived from petroleum.
• Kerosene is of course a fossil fuel since coal, oil shale, and petroleum are considered fossil fuels.
• Hence, incorrect option.

Therefore, option (B) is the correct answer.
