Question Analysis
This question evaluates the student's ability to identify a supersaturated solution based on its behavior when disturbed.

Key Concept Explanation
A supersaturated solution is an unstable solution that holds more dissolved solute than the normal maximum. When a small crystal is added, it triggers the precipitation of excess solute, forming solid particles.

Step-by-step Solution
1. Identify the key concept: The behavior of a supersaturated solution when disturbed.
2. Recognize that adding a small crystal to a supersaturated solution causes it to form solid particles.
