A) Magnesium and chlorine
B) Potassium and manganese
C) Manganese and chlorine
D) Molybdenum and manganese
Explanation
Photolysis of water is associated with pigment system-II and catalysed by presence of $M{n^{2}}^{+}$ and $Cl^{-}$ ions. $4H_{2}O \rightleftharpoons H^{+} + 4OH^{-}$ $4OH^{-}\underset{Mn^{2^{+}},\ {cl}^{-}}{\overset{Z - complex}{\rightarrow}}2H_{2}O + O_{2} \uparrow + 4e^{-}$
