Solution
The correct option is A CAM pathway
In succulents which live in arid conditions, CAM pathway is an adaptation that helps in prevention of water loss and preventing photorespiration. Stomata remains closed throughout the day and opens at night. Carbon dioxide entering through the stomata is converted into organic acids and stored in the vacuoles. These organic acids are broken down into carbon dioxide during the daytime and used for photosynthesis, even though the stomata is closed. This prevents water loss during daytime too.
