Solution

The correct option is A
$4^{\circ} C, 0^{\circ} C$

Generally on cooling water contracts. However, below $4^{\circ} C$ water expands. It expands up to $0^{\circ} C$ .

This is known as the anomalous behaviour of water.

Water on heating from 0 $^{\circ}$ C to 4 $^{\circ}$ C contracts and on further heating it expands.

When water cools, first it expands in volume but below 4°C it starts contracting until it reaches 0°C.
