Answer: 4. Cyclic photophosphorylation involves both PS I and PS II.

Find the incorrect statement.

Cyclic photophosphorylation involves only PS I, so statement 4 is incorrect.
Non-cyclic gives both ATP and NADPH, stroma lamellae have only PS I and lack NADP reductase, and grana have both PS I and PS II: all correct.
