C Correct answer
Explanation

Peroxisomes are essential organelles in photorespiration, where they process glycolate produced by RuBisCO oxygenase activity. The photorespiratory pathway involves three organelles: chloroplast (where glycolate is produced), peroxisome (where glycolate is converted to glycine), and mitochondria (where glycine is decarboxylated). Ribosomes, spherosomes, and centrosomes are not involved in this process.
