Correct answer: A
Z scheme involves both PSI and PSII to transfer electron excited by light starting from PSII uphill to the acceptor, down to the electron transport chain to PSI, which further comprise of excitation of electrons, transfer to another acceptor and finally down hill to NADP+ causing reduction of it to NADPH + H+. Stroma lamella contains PSI only.
