Thermal Expansion

Step 1: Water exhibits an anomalous expansion behavior between C and C. Unlike most substances, its density increases as it is heated from C to C, causing the volume to decrease.
Step 2: At exactly C, water reaches its maximum density, meaning its volume is at a minimum.
Step 3: When heated beyond C, water behaves normally, expanding as the temperature increases, leading to an increase in volume.
Step 4: Therefore, the correct answer is (A). \bigskip
