Vedclass · Answer

(B) The correct answer is $B$. Photosystem-$II$ $(PS-II)$,with its reaction center $P-680$,is responsible for the photolysis of water. During the light-dependent reactions,$PS-II$ extracts electrons from water molecules to replace the electrons lost by the reaction center upon excitation. This process,known as the water-splitting complex or oxygen-evolving complex,results in the release of $O_2$ as a byproduct,along with the production of protons $(H^+)$ and electrons $(e^-)$ according to the equation: $2H_2O \rightarrow 4H^+ + 4e^- + O_2$.
