Solution
The correct option is C Amount of CO2 released during respiration = Amount of CO2 utilised in photosynthesis When the intensity of light is low during a day, the rate of photosynthesis lowers. In this situation, the amount of CO2 released during respiration becomes equal to the amount of CO2 utilised in photosynthesis. This state is called compensation point. This usually occurs during the morning and evening hours.
