Solution
The correct option is A Chloroplasts of bundle sheath cells
C4 pathway occurs in plants growing in adverse environmental conditions. Therefore, to efficiently fix CO2 and prevent photorespiration, fixation occurs in two morphologically and chemically different cells; the bundle sheath and the mesophyll cells. Initially CO2 from the atmosphere is accepted by PhosphoEnolPyruvic acid to form OxaloAceticAcid in the mesophyll cells surrounding the bundle sheath as a ring (Kranz) and then OAA is transported to the bundle sheath cells for decarboxylation and fixation by RuBisCO.So, the correct answer is 'Chloroplasts of bundle sheath cells'
