Solution

The correct option is C Assertion is correct but Reason is incorrect
$Molality = \frac{number of moles of the solute}{mass of the solvent in kg}$
Both, the number of moles of solute and the mass of the solvent are independent of the temperature of the solution.
Hence, Molality is independent of temperature.
Thus, the assertion is correct.
The volume of the solution depends on the temperature.
Hence, the reason is incorrect.
