Which refrigerant is known for having ozone depleting potential?

Explanation:
R22 is recognized for having ozone-depleting potential due to its composition, which includes chlorine. Chlorine is a key element responsible for the depletion of the ozone layer when refrigerants such as R22 are released into the atmosphere. The use of R22 has been significantly phased out under international agreements like the Montreal Protocol because of its environmental impact; as a result, it is being replaced by more environmentally friendly alternatives. In contrast, the other refrigerants listed—R407C, R410A, and R134a—are considered to have negligible or no ozone-depleting potential, as they do not contain chlorine in their chemical structure. This makes them preferable for current applications, as they contribute less to ozone layer depletion.
