Best answer

Correct option (d) Photolysis of water and phosphorylation of ADP to ATP

Explanation :

CO2 is fixed in the stroma of the chloroplast leading to the synthesis of PGA from which glyceraldehyde phosphate is formed. From glyceraldyde phosphate, sugar and starch are formed. All these do not require light. However photolysis of water and phosphyorylation of ADP to ATP requires light energy.
