The answer is the first sentence; "As the number of electrons in a molecule increases, the London dispersion force increases." :)

Answer:

As the number of electrons in a molecule increases, the London dispersion force increases.

Explanation:

The London dispersion forces are the inter molecular interactions which are the weakest of all the inter molecular interactions.

They are forces due to asymmetric distribution of electrons in an atom which generates  temporary dipole. This dipole of caused distortion in second atom and creates another dipole. now these two dipoles are the cause of electrostatic attractions.

Thus if the number of electrons will increase the London dispersion force will increase.
