The correct option is
C Oxidative enzymes
Peroxisomes are single membrane covered organelles, which take part in oxidation reactions other than those of respiration. Peroxisomes take part in oxidative breakdown of extra biochemicals like purines, amino acids, alcohols, toxins etc. In mesophyll cells, peroxisomes interact with chloroplasts and mitochondria to take part in photorespiration.
So, the correct answer is 'Oxidative enzymes'
