Answer:

C. The temperature decreased.

Step-by-step explanation:

When the particles of a gas slow down and collect at the bottom of the container, forming a rigid structure, it indicates a phase change from a gas to a solid. This change is known as deposition or condensation. It typically occurs when the temperature decreases, causing the gas particles to lose energy and transition into a more ordered and compact arrangement.
