detailed solution

Correct option is B

Several mesophyll cells of C4 plants are involved in gathering CO2 of atmosphere to form C4 acids. These are transported to bundle sheath cells and subjected to decarboxylation to increase intracellular concentration of CO2 in bundle sheath cells due to decarboxylation to enhance the RuBisCO carboxylation activity.
