Solution

The correct option is B If both (A) and (R) are true, but (R) is not the correct explanation of (A).

Acidic zeolites are as catalysts in petrochemical industries. An important zeolite catalyst used in the petroleum industry is ZSM-5. It converts alcohols directly into gasoline by first dehydrating them so that a mixture of hydrocarbons is formed.

Zeolites are porous catalysts having sieve-like structure. So, both assertion and reason are true but the reason is not the true explanation of assertion.
