B

Explanation:

The proton motive force; is the free energy released during the oxidation of NADH or FADH2 and it is stored both as an electric potential and a proton concentration gradient across the inner membrane.

The purpose of proton motive force is that the movement of protons back across the inner membrane, driven by this force, is used to the synthesis of ATP from ADP and Pi by ATPase / ATP synthase (F0F1 complex).
