In C4 plants, the initial fixation of CO2 occurs in mesophyll cells, forming a 4-carbon compound. This compound then travels to bundle sheath cells, where it releases CO2. What is the PRIMARY advantage of this spatial separation of CO2 fixation and the Calvin cycle?

I. In ${C_3} -$ plant, Calvin pathway takes place in mesophyll cell

II. In ${C_4} -$ plant, Calvin pathway takes place in the mesophyll cell

PEP carboxylase

I. is involved in atleast some $C{O_2}$ fixation in both ${C_3}$ and ${C_4} -$ plants

II. Catalyses the reaction of fixing $C{O_2}$ into pyruvic acid in bundle sheath cells

III. is capable of fixing $C{O_2}$ more efficiently at lower atmospheric $C{O_2}$ concentration than RuBP carboxylase
