Solution
The correct option is B Crassulaceae
CAM stands for crassulacean acid metabolism because it was first studied in members of the plant family Crassulaceae (Bryophyllum). CAM is the fixation of carbon dioxide by plants in arid condition. In normal conditions, the opening of the stomata is always connected with the large losses of water. To inhibit this loss during intense sunlight, CAM plants have developed a mechanism which allows the uptake of carbon dioxide during the night. They are more common than C4 plants and include cacti and a wide variety of other succulent plants. So, the correct answer is 'Crassulaceae'.
