Best answer

Answer: 4. (c) and (d) only

Check each statement.

(a) Solid \(\mathrm{CO_2}\) (dry ice) is the refrigerant for ice-cream and frozen food, not the gas. The statement says \(\mathrm{CO_2(g)}\), so it is treated as incorrect.
(b) \(\mathrm{C_{60}}\) has 20 six-membered and 12 five-membered rings. The statement has it reversed, so it is incorrect.
(c) ZSM-5 zeolite converts alcohols into gasoline (hydrocarbons). Correct.
(d) CO is a colourless, odourless gas. Correct.

Correct statements: (c) and (d) only, option (4).
