Solution

The correct option is D $M o l a l i t y$
$M o l a l i t y = \frac{n u m b e r o f m o l e s o f s o l u t e}{m a s s o f s o l v e n t i n k i l o g r a m s}$

Since mass is unaffected by the change in temperature, hence molality is independent of temperature.

Hence, the correct option is $D$
