Best answer
Correct answer is (b) Zeolite

Easy explanation: The zeolites used in catalytic cracking are chosen to give high percentages of hydrocarbons with between 5 and 10 carbon atoms – particularly useful for petrol. The zeolite catalyst has sites which can remove a hydrogen from an alkane together with the two electrons which bound it to the carbon.
