Solution
The correct option is C CO2 compensation point
The CO2 compensation point of a green plant is the CO2 concentration at which the rate of photosynthetic CO2 uptake is equal to the rate of respiratory CO2 loss.
Extinction point is the point of minimum oxygen concentration at which aerobic respiration takes place.
CO2 saturation point is the maximum amount of CO2 that the plant can uptake.
CO2 fixation is the point where carbon dioxide enters a cycle.
