Which statement about HFO refrigerants such as 1234yf is true?

Explanation:
These refrigerants are designed to minimize climate impact, especially in terms of global warming potential. 1234yf has a GWP of about 4, which is far lower than traditional HFCs like R-134a (around 1430). That makes the statement about having very low GWP true. They do not deplete the ozone layer, so their ozone depletion potential is zero. They are not always non-flammable—1234yf is considered mildly flammable (A2L)—so the claim that they are always non-flammable is not accurate. They certainly do not have high GWP.
