Solution
The correct option is C Cheimoosmotic theory
As per Peter Mitchell's chemiosmotic coupling hypothesis, outward pumping of protons across the inner chloroplast or mitochondrial membrane result in accumulation of protons between the outer membrane and inner membrane. A proton gradient is thus established. As proton now flow back passively down the gradient the proton motive force is utilized to synthesize ATP.
