D Correct answer
Explanation

Water reaches its maximum density at approximately 4°C, not at its freezing point (0°C). This unusual property occurs because the hydrogen bonds in water create a more compact molecular structure around 4°C. Below this temperature, water begins to expand as it forms the crystalline structure of ice.
