Detailed Solution

London dispersion forces depend on the atomic/molecular weight of the material.

The atoms/molecules with more weight have more electrons, and stronger London forces. This force also depends on number of polarizable electrons.

This force is inversely proportional to the sixth power of the distance between the particles.

Generally $\propto \frac{1}{T}$

Thus, all are correct option.
