B) Butane
C) Methane
D) None of these

Answer 1

Hint: It is a general question that one should know or learn, it is about the cooking gas. LPG is nothing but the Liquefied Petroleum Gas composed of the hydrocarbons. It is mainly consisting of propane and butane. It is the bio product of natural gas and oil refining.

Complete step by step answer:
To meet the requirements of commercial natural gas the gases that are present as impurities that are ethane, propane, butane and water. This separated propane and butane gas are used as the Liquefied Petroleum Gas also extracted during the oil extraction in the refineries.
This Liquefied Petroleum Gas is used for the purpose of cooking and heating and is mostly having a high demand due to its high use.
Using this Liquefied Petroleum Gas for the cooking purpose also helps in decreasing the pollution. If we burn the fossil fuels for the cooking purpose it releases the gases like $C{{O}_{2}}$ which pollutes the environment if the level of it exceeds the environment.
Also this Liquefied Petroleum Gas supplies the quick heat and is more efficient than stoves which burn biomass and it can be easily transportable. But we should be careful while using it because it may lead to a huge explosion if there is any leakage of it. A small fire can catch it and explode if there is a leakage so we should take care of it.

So, the correct answer is “Option B”.

Note: There are a wide number of advantages of this Liquefied Petroleum Gas which is having a wide variety of uses and having less pollution. Hence LPG mainly consists of Butane which has a wide variety of uses.
