C Correct answer
Explanation

During photorespiration, the oxidation of glycolate in the peroxisome produces hydrogen peroxide as a byproduct, which is subsequently broken down by the enzyme catalase into water and oxygen. Thus, the peroxisome is the primary site of H2O2 generation in this pathway.
