Solution

The correct option is C C
During photosynthesis, leaves take in atmospheric CO $_{2}$ and release O $_{2}$ through stomata, microscopic pore structures in the leaf epidermis. A pair of guard cells (shown by C in the diagram) surrounds each stoma and these cells control the opening and closing of the stomatal pore between them.
