Which of the following concentration factors affected by change in temperature?

We know that the molarity of a solution is written as, no.of moles Molarity of solution = volume of solution in litres Molarity depends on the volume of the solution. Volume is affected by the temperature. An increase in temperature increases the kinetic motion of molecules which causes the change in concentration of a solution. On the other hand, molality, mole fraction, weight fraction are mass-dependent concentration terms that are not affected by the temperature. Thus, (a) is the correct option.
