Light reactions of photosynthesis are carried out by four major protein complexes: Photosystem I (PSI), photosystem II (PSII), the cytochrome b6f complex and ATP synthase. The following are certain statements on PSII:

a. Red light absorbed by photosystem II (PSII) produces a strong oxidant and a weak reductant.

b. Far-red light absorbed by photosystem II (PSI) produces a weak oxidant and a strong reductant.

c. The strong oxidant generated by PSII oxidizes water,

d. The strong reductant generated by PSII oxidizes water
