Which refrigerant is a natural refrigerant?

Explanation:
Natural refrigerants come from natural sources or processes and typically have very low environmental impact. Hydrocarbons like isobutane, known as R-600A, are classic natural refrigerants. R-600A has negligible ozone depletion potential and a very low global warming potential, making it a common example of a natural refrigerant used in small refrigeration systems. The other options are synthetic refrigerants: R-134a, R-22, and R-32 all have higher global warming potential and/or ozone depletion potential, so they’re not considered natural. A note to keep in mind is that R-600A is flammable, so safety considerations are important.
