Best answer
The correct option is (d) Chemiosmosis

The best explanation: There is a pH gradient across the thylakoid membrane, which provides a proton motive force. This creates chemical potential energy for the production of ATP from ADP and inorganic phosphate is called chemiosmosis. Peter Mitchell proposed this theory.
