The main idea is EPA’s leak repair rule for comfort cooling equipment: if a system holds a fairly large amount of refrigerant, its leaks must be repaired when the annual leak rate is above a certain threshold. For comfort cooling appliances, the trigger is when the refrigerant charge is more than 50 pounds, and the leak rate exceeds 15% per year. That combination is the reason the correct choice is 50 pounds and 15%. The other options mix different charge amounts or different leak-rate percentages that do not match the regulatory thresholds for these systems. For context, larger systems have stricter repair requirements because they have greater potential for refrigerant loss, so the 50-pound and 15% rule is a standard benchmark you’ll frequently see.
