Solution

The correct option is B ADP + Inorganic $P O_{4}$ $L i g h t e n e r g y - ------ \to$ ATP
Phosphorylation means addition of phosphorous. When a molecule of ADP is phosphorylated, it results into synthesis of energy rich ATP. When this process occurs in presence of light it is called as photophosphorylation.
