If a refrigerant has an ODP of 0.055, it contains which and could be which refrigerant?

Explanation:
ODP shows how much a refrigerant can harm the ozone layer, and chlorine is the main contributor. Fluorine doesn’t drive ozone depletion in the same way, so a small ODP like 0.055 means chlorine is present but not in a highly ozone-depleting combination. A refrigerant with that ODP is R-22, which is CHClF2 and contains chlorine (along with fluorine). Freon-12, by contrast, has a much higher ODP (around 1.0), so it wouldn’t match 0.055. So the statement that it contains chlorine and could be R-22 is the best fit.
