D) The water is releasing energy as its temperature decreases, and that energy is absorbed by the surroundings.

Explanation:

When the temperature decreases it loses energy to the surroundings. When water cools and then freezes to ice it becomes a solid which has a lower energy compared to liquid and gas. Solid is more compact and little or no collision occurs between its particles.

This means energy was lost during the process of freezing to ice. The energy lost is normally absorbed by the surrounding environment.
