Solution

The correct option is B Molality and mole fraction
We know Molarity= $\frac{N o . o f m o l e s o f s o l u t e}{1 L o f s o l u t i o n}$
Normality= $\frac{N o . o f g r a m e q u i v a l e n t w e i g h t o f s o l u t e}{1 L o f s o l u t i o n}$
Both Molarity and Normality depends on volume of solution and as we know volume varies with temperature variation.
Whereas Molality= $\frac{N o . o f m o l e s o f s o l u t e}{1 k g o f s o l v e n t}$
Molality is independent of temperature as mass is independent of temperature.
Also, Mole fraction= $\frac{N o o f m o l e s}{T o t a l m o l e s}$ is independent of temperature.
