detailed solution

Correct option is A

Both grana lamellae and stroma lamellae have PSI. PSII is present only in grana lamellae. Hence, non-cyclic electron transport mainly takes place in grana lamellae and cyclic electron transport and phosphorylation predominantly takes place in stroma lamellae.
