The correct option is:

C. ATPase enzymes consist of Fo and F1 units.

Explanation:
A. This is incorrect. Stroma lamellae membranes do contain both photosystem II (PSII) and photosystem I (PSI).

B. This is incorrect. When PS I is functional, electrons flow in a cyclic way, not a noncyclic way.

C. This is correct. ATPase enzymes consist of Fo and F1 units. Fo is embedded in the thylakoid membrane and F1 is found in the stroma.

D. This is incorrect. NADP reductase is not a part of PSII; it is involved in the reduction of NADP+ to NADPH and is associated with the photosystem I complex.
