Answer:
the drive-reduction theory
Explanation:
The drive-reduction theory is one of the theories of motivation.
This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.
The theory targets homeostasis or biological balance.
When there is a need such as lack of water, the need would cause a drive to be developed (thirst).
The drive would activate a response (search for water to drink).
The response is then terminated when the need has been satisfied.

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.
