Hint: LPG is a liquefied petroleum gas. It is most commonly used gas for cooking, in heating appliances and even in vehicles. The percentage composition of LPG is butane as 70 % and propane as 30 %. It is obtained from crude oil and natural gas.

Complete answer :
We all have studied about LPG. The LPG is a liquified petroleum gas. As the name suggests, it is liquified i.e. converted into liquid form and is a petroleum gas. Thus, it is also extracted from crude oil and natural gas like other energy resources. It is a non-renewable source of energy. The major components of LPG are propane and butane. Some other hydrocarbons are also present but they are in small concentrations. The mixture of propane and butane is a flammable mixture.
The percentage composition is as -
Butane = 70 %
Propane = 30 %
Thus, the correct answer is butane.

So, the option b.) is the correct answer.
