Solution

The correct option is D Both (B) and (C)
'Z-scheme' show the transfer of electrons involving photosystem I and II. The photosynthesis process in chloroplasts begins, when an electron of P680 of PSII attains a higher-energy level. This energy is used to reduce a chain of electron acceptors that have subsequently lowered redox-potentials. This chain of electron acceptors is known as an electron transport chain. When this chain reaches PS I, an electron is again excited, creating a high redox-potential. The electron transport chain of photosynthesis is often put in a diagram called the z-scheme, because the redox diagram from P680 to P700 resembles the letter 'z'.
