(D) The correct option is $D$. Atmospheric carbon dioxide $(CO_2)$ is a limiting factor for photosynthesis. At a concentration of $300 \, ppm$ (which is approximately the current ambient level),plants can perform photosynthesis efficiently. Since $CO_2$ is a primary substrate for the Calvin cycle,this concentration supports optimal carbon fixation,allowing plants to thrive and grow well.
