Cyclic photophosphorylation involves both $PS-I$ and $PS-II$.

(D) In non-cyclic photophosphorylation,both $PS-II$ and $PS-I$ work in series,resulting in the production of both $ATP$ and $NADPH + H^+$.Stroma lamellae lack $PS-II$ and $NADP$ reductase enzyme,so they only perform cyclic photophosphorylation involving $PS-I$.Grana lamellae contain both $PS-I$ and $PS-II$,allowing for non-cyclic electron flow.Cyclic photophosphorylation involves only $PS-I$,not $PS-II$. Therefore,the statement that cyclic photophosphorylation involves both $PS-I$ and $PS-II$ is incorrect.
