In the Z scheme, the electron carriers between PS II and PS I include

(a) ferredoxin, NADP reductase and NADP⁺ Your answer
(b) plastoquinone, the cytochrome b₆f complex and plastocyanin Correct
(c) RuBisCO, PEP carboxylase and carbonic anhydrase Your answer
(d) CF₀, CF₁ and the water-splitting complex Your answer

Your answer: Correct answer: (b)

Explanation

Why (b) is correct

Between PS II and PS I, the electron carriers are plastoquinone, the cytochrome b₆f complex and plastocyanin.

Why the other options are wrong

(a) · your answer Ferredoxin and NADP reductase come after PS I.
(c) · your answer These are enzymes of carbon fixation.
(d) · your answer CF₀ and CF₁ are parts of ATP synthase; the water-splitting complex is before PS II.

NCERT point: Carrier order: PQ → cyt b₆f → PC.
