The compression ratio of petrol engine is 6-10 and compression ratio of diesel engine is 15-22. Always should take nearer value. So 'B' is nearest Answer.

This range is used because if more compression is used there is the possibility of occurrence of knocking which can affect the system adversely.

Petrol have low ignition temperature. Because of that if compressed beyond that, it will automatically ignite and combust. This is detonation.

For petrol engine the compression ratio range from 7:1 to 10:1 and diesel engine its range from 14:1 to 20:1.

Generally petrol or gasoline compression ratio are 6 to 12 and diesel are 16 to 24.

Petrol & diesel both viscosity difference, its calorific value also different.

That's why the diesel engine mileage is higher than petrol engine.
