D Correct answer
Explanation

Evaporation is a surface phenomenon that occurs at all temperatures above 0°C, not just at the boiling point. Water molecules escape from the surface when they gain enough kinetic energy, which happens at any temperature. The boiling point (100°C) is when evaporation occurs throughout the liquid volume, not just at the surface. Options A, B, and C incorrectly suggest specific temperatures are required.
