Gas to liquid is condensation (like on the side of your lemonaide glass!)

Deposition skips liquid (who needs 'em?) and is a change from gas to solid.

Desublimation is another term for deposition. I guess there is still some ambiguity here.

It's debatable. I essentially believe the answer is deposition, but thank you @Harkirat, for your insight.

Even in science sometimes they leave ambiguities....I feel "reverse sublimation" should be the correct name that they should coin.....☺

The answer is NOT condensation.
