Solution

The correct option is A Help in oxidation of glycolate
Peroxisomes lie between chloroplasts and mitochondira in the plant cell and serve to pass the 2-carbon products of oxygenation on for further metabolism. In the chloroplast, the phosphoglycolate is dephosphorylated. Glycolate is transported to the peroxisome, where molecular oxygen further oxidizes it into glyoxylate. The product is hydrogen peroxide, which is rapidly broken down by catalse to water and oxygen. The glyoxylate is amidated to the amino acid glycine in the peroxisome.
So, the correct answer is 'Help in oxidation of glycolate'
