- Sublimation occurs only when the temperature is above freezing true or false

False

Explanation:

Even at temperatures below 0°C, solid H 2O will slowly sublime. For example, a thin layer of snow or frost on the ground may slowly disappear as the solid H 2O sublimes, even though the outside temperature may be below the freezing point of water. Similarly, ice cubes in a freezer may get smaller over time

i believe the answer is d.
