To solve this problem, let's analyze each statement individually:$\\$(a) $$CO$_2(g)$ is used as a refrigerant for ice-cream and frozen food.$\\$• This statement is incorrect. CO$_2$ is not typically used as a refrigerant for ice-cream and frozen food.$\\$• Instead, ammonia or other refrigerants are more commonly used.$\\$(b) The structure of C$_60$ contains twelve six-carbon rings and twenty five-carbon rings.$\\$• This statement is incorrect. C$_60$, also known as Buckminsterfullerene,$\\$• contains twenty hexagonal (six-carbon) rings and twelve pentagonal (five-carbon) rings.$\\$(c) ZSM-5, a type of zeolite, is used to convert alcohols into gasoline.$\\$• This statement is correct. ZSM-5 is a catalyst used in the petrochemical industry$\\$• to convert alcohols into hydrocarbons, which can be used as gasoline.$\\$(d) CO is a colorless and odorless gas.$\\$• This statement is correct. Carbon monoxide (CO) is indeed a colorless and odorless gas.$\\$Based on the analysis, the correct statements are (c) and (d).$\\$Therefore, the correct option is Option 3: (c) and (d) only.
