Text Solution

Verified by Experts

The correct Answer is:
A
CAM (Crassulacean Acid Metabolism) plants open stomata only at night (when temperatures is low and humidity is high) to cause lesser loss of water (e.g. agave, opuntia, etc.) So, CAM photosynthesis is a carbon fixation pathway that evolved in some pklants as an adsptation to arid condition.
