A factory-manufactured, factory-charged, hermetically sealed unit contains exactly 5 pounds of refrigerant. Based on the Type I definition, which conclusion is correct?

A
It qualifies as a small appliance because it is factory-manufactured, charged, and sealed, and its charge does not exceed 5 pounds.
B
It does not qualify because small appliances must contain less than 5 pounds of refrigerant.
C
It does not qualify because a small appliance must have a permanent service valve.
D
It qualifies only if it is a household refrigerator or freezer.
