What is the benefit of separating the light and carbon reactions into different cells in C4 plants?

What is the benefit of separating the light and carbon reactions into different cells in C4 plants?

Select one:

a. CO2 to O2 ratios are maintained in the bundle sheath cells, even with a large number of stoma closed, because the light reactions are generating oxygen in a different cell.

b. Since the light reactions occur closer to the leaf surface oxygen can escape more easily.

c. More ATP remains to power metabolism in the mesophyll cells because the carbon reactions are occurring in the bundle-sheath cells.

d. The enzyme required to make the 4-carbon compound (that C4 is named after) is only found in mesophyll cells and to have enough energy and room for the Carbon cycle these reactions must move to a different cell.
