The correct answer is - B. lower environmental availability of CO2
Explanation:
In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4 to avoid photorespiration.
These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.
They release CO2 (just like us, when we breathe). But, when plants are photosynthesizing. They release the oxygen through the same pores that allow the CO2 to enter their leaf cells.
