The fixation of CO 2 by PEP carboxylase functions to

The fixation of CO 2 by PEP carboxylase allows plants to close stomata without the occurrence of photorespiration, which in turn reduces water loss by the plant. It does not allow plants to photosynthesize in the dark or concentrate CO 2 for use in photosynthetic cells. Therefore, the best choice is B.
