Since C4 plants have a competitive advantage over plants possessing the more common C3 carbon fixation pathway under conditions of drought, high temperatures, and nitrogen or CO 2 limitation and C3's photosynthetic efficiency suffers during hot dry season because of photorespiration, t he answer is more likely letter a. C4 carbon fixation is an adaptation for plants exposed to high light intensity.
