Experiments 1, 2 and 3 were conducted wherein synthetic vesicles containing `F_(0)-F_(1)` ATP synthasev were prepared and incubated overnight in a tube. Subsequently, the vesicles were transferred to another tube which alsao contained ADP and Pi (inorganic phosphate).

A. A proton gradient across the vesicular membrane will be present in both experiments 1 and 2 at the time of transfer.
B. As a consequence of the proton gradient, ATP will be synthesised in both experiments 1 and 2.
C. ATP will be synthesised in experimants 3 because Fo-F1 ATP synthase has the inherent property to catalyse the synthesis of ATP from ADP and Pi.
D. ATP will be synthesised in experimants 2 because the proton has to flow out of the vesicles through the `F_(0)-F_(1)` ATP synthase for ATP synthesis.
