CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix 
into organic acids during the night.
The correct option is a.
As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.
During the day, the malate is transferred to chloroplasts where it is transformed back to 
, which is then utilised during photosynthesis. At night, the is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected , which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.
