Explanation:

To solve this, we analyze each option:

• Option a: Sublimation is defined as the transition of a substance from the solid phase directly to the gas phase without passing through the liquid phase.
• Option b: Evaporation is the process of a liquid turning into a gas (vapor), so it starts from the liquid state, not solid.
• Option c: Condensation is the process of a gas turning into a liquid, which is the opposite of what the question describes.

So the correct option is a as it matches the description of the process from solid to gas without becoming liquid.

Answer:

a. Sublimation
