The ban on chlorofluorocarbons was not specifically aimed at which of the following groups?

The focus of the ban on chlorofluorocarbons (CFCs) was primarily on the production and use of these substances due to their significant contribution to ozone depletion. The Montreal Protocol, which was established to phase out the use of ozone-depleting substances, targeted manufacturers and suppliers of CFCs more directly than those who merely utilize them.

While companies that produce, export, or import CFCs are directly affected by regulations designed to reduce environmental impacts, companies that use CFCs, such as those in manufacturing and refrigeration sectors, have been given a more gradual timeline to transition to alternatives. This distinction indicates that the ban was less directly aimed at the end-users of the gas, as these companies typically needed time and support to adapt to the changes.

Thus, option A is correct because the ban did not singularly target companies using CFCs but instead focused more explicitly on those engaged in the production, import, and export of these harmful substances.
