D Correct answer
Explanation

 On heating from 0oC upto 4oC its volume decreases, reaching a minimum at 4oC, such that the density of water is maximum at 4oC. On heating further, water behaves like any other liquid. Similarly, during cooling process, the volume of water decreases up to 4oC, reaching a minimum at 4oC. If further cooled upto 0o C, its volume increases instead of decreasing and hence, density of water at 0oC is lesser than that at 4oC.
