CAM (Crassulacean acid metabolism) is the most favorable photosynthetic mode in a desert environment because it allows the plant to reduce water loss by opening their stomata at night and taking in CO2, which is stored in the form of organic acids until the next day when it is converted to sugar by photosynthesis. This allows the plant to perform photosynthesis during the day with closed stomata, reducing water loss due to evaporation. Other options (B, C, D, and E) are not as favorable in a desert environment because they do not provide the same level of water conservation as CAM.
