Solution
The correct option is B Mesophyll cells
In C4 plants, the Hatch and Slack pathway involves two carboxylation reaction, one taking place in chloroplast of mesophyll cells and other in chloroplast of bundle – sheath cells. In mesophyll cells, phosphoenol pyruvate (PEP) is carboxylated to oxaloacetate (OAA) which is then reduced to malic acid.
