Assertion (A) : A glass of water is filled at 4∘C4^{\circ} \mathrm{C}. Water will overflow, if temperature is increased or decreased. (Ignore expansion of glass).

Reason (R) : Density of water is minimum at 4∘C4^{\circ} \mathrm{C}.
View answer and explanation
Correct option: C
If Assertion is true, but the Reason is false.
Option C (If Assertion is true, but the Reason is false) is correct because water expands when cooled below 4°C, and also expands when heated above 4°C, but its density is maximum at 4°C, not minimum.
