Explanation:
Regarding refrigerant leaks on small appliances such as household refrigerators, the correct statement is that refrigerant leaks on small appliances should be repaired promptly, and some may require reporting (Option C). Although the regulations can vary based on the jurisdiction, typically not all refrigerant leaks must be reported to the authorities, unless they involve a significant amount of ozone-depleting substances or exceed certain thresholds. Small appliances like refrigerators utilize a coolant in a cycle to remove heat from the inside, and any leak can not only reduce the efficiency of the refrigerator but also potentially release harmful substances into the atmosphere. It's essential to address leaks to maintain the appliance's performance and prevent environmental damage.
