Answer: c) This process is an example of sublimation.

Explanation:

When liquid is further heated, the molecules gain more kinetic energy and molecules move farther and convert to gaseous state and the process is called vaporization.

Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.

Deposition is a process of converting a substance from gaseous state to solid state without the formation of liquid at constant temperature.

In liquid the particles are loosely packed as the inter molecular forces of attraction are not that strong. As they are cooled, the kinetic energy of the molecules decreases and thus the molecules start getting closer and convert to solid state. The process is called freezing.
