Octane rating or octane number is a standard measure of the performance of a motor- or aviation fuel. The higher the octane number, the more compression the fuel can withstand. fuels with a higher octane rating are used in high performance petrol engines that require higher compression ratios. thus it reflects the quality of fuel.

A cetane number is the measure of the quality of the diesel . Higher cetane number indicates that the fuel ignites more readily when sprayed over hot compressed air.

The following fuels are present in the heavy oil obtained during petroleum distillation 1. Gas oil  2.Fuel oil and Diesel oil.

So all the given options are correct.

Hence option D is correct.

Unisol process is a regenerative method for not only extracting or removing mercaptans but also some of the nitrogen compounds. In this process first gasoline is washed counter-currently with aqueous caustic methanol solution. The spent caustic is regenerated in a stripping tower where the methanol, water and mercaptans are extracted.

LPG is liquified petroleum gas used for cooking purpose.

Main component of CNG is methane (the simplest alkane). the other components present are:

Natural gas is found in deep underground rock formations in coal beds and in oil beds.

Chemical fuels react with oxygen (combustion) and releases their energy.

Sun, Biomass, Wind are renewable sources which can be replenished within human lifeitme. Whereas natural gas is non-renewable source.

Liquefied petroleum gas or it is also called liquid petroleum gas abbreviated as LPG. 

Also referred to as propane or butane, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances and cooking equipment.
