Solution

The correct option is C Assertion is correct but Reason is incorrect
Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). It involves the simultaneous change of chemical composition and physical phase and is irreversible.It is used in obtaining petroleum.
Hydrocarbon Pyrolysis involves endothermic reactions. So statement-2 is wrong.
Hence $C$ is the correct option.
