Reason:
ATP synthesize in cyclic photophosphorylation is not associated with NADPH formation.

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
In case of cyclic photophosphorylation, the electron, while passing between ferredoxin and plastoquinone and/or over the cytochrome complex the electron loses sufficient energy to form ATP from ADP and inorganic phosphate.
