Before the Montreal Protocol restrictions, CFCs served as (1) blowing agents for plastic foams, (3) precision cleaners for electronic components, and (4) propellants/pressurising agents in aerosol cans. They were never used in manufacturing tubeless tyres, making statement 2 incorrect; therefore statements 1, 3 and 4 alone are true.
