For the last question it's either C or D.
Answer:
a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed
Explanation:
C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.
Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.
<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>
