Hi, the answer is C but I’m not sure with reasoning / concept.

Hey,

When larger alkane molecules are cracked, they form smaller alkane molecules and alkene molecules.

general formula of Alkanes are 2n+2 , so this gives opt A and D

general formula of Alkenes are 2n so this gives opt B and E

Moreover, Hydrogen could also be formed so this rules out opt F too.

Opt C is not an alkane or alkene so that would be the answer.
