I think C is the answer.

Answer is right, cetane number indicates delay period of combustion in pressure condition. Higher cetane number gives higher compression ratio.

Fuel with lower cetane no have more ignition delay. So, the delay period is right.

The correct answer is D, cetane number is used to measure the delay period in case of diesel engine but Cetane number and octane numbers are used to measure ignition quality in case of petrol (gasoline) engine.

Yes, it indicates ignition quality.
DHARMENDER PRAJAPATI said:

Ignition quality is the correct answer.

This is decided as per knock value of the fuels.

Delay period is the right one.

The main difference between cetane and octane ratings is that the octane rating represents how well a fuel can resist pre-ignition due to compression"ensuring the fuel ignites only from a spark from the spark plug.
However, the cetane number measures the delay in the ignition time of the fuel. In other words, it is how minimized the delay is between when the fuel is injected into the chamber and when the combustion begins.
