Solution
The correct option is A cyclic photophosphorylation
Photophosphorylation is the synthesis of ATP from ADP and inorganic phosphate in the presence of light.
When the two photosystems work in a series, first PS II and then the PS I, a process called non-cyclic photo-phosphorylation occurs. The two photosystems are connected through an electron transport chain in the Z scheme.
When only PS I is functional, the electron is circulated within the photosystem and the phosphorylation occurs due to cyclic flow of electrons. Cyclic photophosphorylation occurs when only light of wavelength of 700nm is available for excitation.
