The freezing point of ice is

Options

A. `0^@C`
B. `4^@C`
C. `-4^@C`
D. none of these

Answer

To solve the question regarding the freezing point of ice, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Freezing Point**:
- The freezing point is the temperature at which a liquid turns into a solid. For water, this is a critical temperature to know.

2. **Identify the Freezing Point of Water**:
- Water freezes at 0 degrees Celsius (°C) under standard atmospheric conditions. This is a well-known fact in physics and chemistry.

3. **Analyze the Options Provided**:
- The options given are:
1. 0 degrees Celsius
2. 4 degrees Celsius
3. -4 degrees Celsius
4. None of these

4. **Evaluate Each Option**:
- Option 1: 0 degrees Celsius - This is the correct freezing point of water (and hence ice).
- Option 2: 4 degrees Celsius - This is not the freezing point; it is actually the temperature at which water is at its maximum density.
- Option 3: -4 degrees Celsius - This is incorrect; it is below the freezing point of water.
- Option 4: None of these - This is also incorrect since we have identified the correct freezing point.

5. **Conclusion**:
- The correct answer is option 1: 0 degrees Celsius.

### Final Answer:
The freezing point of ice is **0 degrees Celsius**.
