The correct choice is (d) Atmospheric CO2
 
The explanation is: The plants use atmospheric CO2 as a source of carbon dioxide for food production. They produce food using photosynthesis. Photosynthesis is a process in which producers (green plants) in the presence of CO2, water, sunlight, and chlorophyll yield energy and oxygen is released in the form of gas.
