  • A Liquid → Gas
  • B Solid → Liquid
  • C Gas → Liquid
  • D Gas → Solid
Correct Answer: Option A
Explanation:
The phase change from a liquid to a gas involves an increase in entropy. In the gas phase, molecules have higher degrees of freedom and are more dispersed compared to the liquid phase, resulting in higher entropy change.
