Solution:

Molarity is a function of volume which is a function of temperature as volume changes with temperature. But molality depends on the mass of solute and solvent which are independent of temperature.
Molarity is number of moles per liter volume of the solution and molality is number of moles of solute particles dissolved in per kg mass of solvent.
Both Assertion and Reason are incorrect
