(B) The structure of C60 contains twelve six carbon rings and twenty five carbon rings. (C) ZSM-5, a type of zeolite, is used to convert alcohols into gasoline. (D) CO is colorless and odourless gas.

1. (A) and (C) only
2. (A) and (C) only
3. (C) and (D) only
4. (A), (B) and (C) only

Correct answer: (C) and (D) only

Solution

Statements (C) and (D) are correct. ZSM-5 is indeed used to convert alcohols into gasoline, and CO is a colorless and odorless gas. Statement (A) is incorrect because CO2 is not commonly used as a refrigerant for ice cream and frozen food. Statement (B) is incorrect as the structure of C60 contains twelve pentagonal and twenty hexagonal rings.
