The Correct Option is D
Approach Solution - 1
Water freezes at a specific temperature and pressure. The phase change from liquid to solid occurs at a point known as the freezing point. Under standard atmospheric conditions:
Freezing Point: 0 ºC
Atmospheric Pressure: 1 atm
This is because the molecules in water slow down enough to form a crystalline structure, which results in the transition of water from a liquid state to solid ice. Therefore, considering the options provided, the correct conditions for the freezing of water are:
0 ºC, 1 atm
As a result, the freezing of water takes place in these conditions:
- Temperature of 0 ºC
- Atmospheric Pressure of 1 atm

Approach Solution -2
Concept: Freezing is the process where a liquid turns into a solid when its temperature is lowered below its freezing point.
For water, this occurs at:
- Temperature: 0 ºC
- Atmospheric Pressure: 1 atm (standard atmospheric pressure)
Correct Answer: 0 ºC, 1 atm
