The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Density**: Density is defined as mass per unit volume. For liquids, this property can change with temperature. 2. **Behavior of Water**: Water is unique in its behavior compared to most substances. As water is cooled from a higher temperature, it becomes denser until it reaches a temperature of 4°C. 3. **Temperature and Density Relationship**: Below 4°C, water starts to expand as it cools further, which means its density decreases. This is contrary to what happens with most other substances, which continue to become denser as they cool. 4. **Conclusion**: Therefore, the maximum density of water occurs at 4°C. 5. **Final Answer**: The density of water is maximum at **4°C**.
