Which of the following process involves the change of a state from liquid to solid

Options

A. Melting of ice cubes
B. Drying of clothes
C. Formation of water vapour
D. None of these

Answer

To solve the question "Which of the following process involves the change of a state from liquid to solid?", we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify a process that changes a substance from a liquid state to a solid state.

2. **Analyze the First Option**:
- **Melting of Ice Cubes**: This process involves ice (which is solid) turning into water (which is liquid). Therefore, this option does not represent a change from liquid to solid.
- **Conclusion**: This option is incorrect.

3. **Analyze the Second Option**:
- **Drying of Clothes**: When clothes dry, the water (liquid) evaporates into water vapor (gas). This process does not involve a change from liquid to solid.
- **Conclusion**: This option is also incorrect.

4. **Analyze the Third Option**:
- **Formation of Water Vapour**: This process involves liquid water turning into water vapor, which is a gas. Again, this does not represent a change from liquid to solid.
- **Conclusion**: This option is incorrect as well.

5. **Final Conclusion**: Since none of the options provided involve a change from liquid to solid, the correct answer is "none of these".

### Answer: None of these (Option 2d)
