Which of the following classes refers to a refrigerant that is not flammable at all?

Explanation:
Flammability classification for refrigerants shows how easily a substance can ignite. A refrigerant that is not flammable at all falls into the nonflammable category. This means it cannot sustain combustion under normal conditions, so it poses much less fire risk than those described as flammable or with any level of flammability. The other terms indicate increasing ignition potential, which isn’t the case for a nonflammable refrigerant. Keep in mind, even nonflammable refrigerants still require proper handling and can have other hazards, but regarding fire, they do not ignite.
