Vedclass · Answer

(A) Pigment system-$II$ ($PS$-$II$) is a protein complex involved in the light-dependent reactions of photosynthesis.It contains the oxygen-evolving complex $(OEC)$ which is responsible for the photolysis of water $(2H_2O \rightarrow 4H^+ + 4e^- + O_2)$.This process releases electrons to replace those lost by the reaction center chlorophyll $P_{680}$ and releases oxygen as a byproduct.Therefore,the correct option is $A$.
