c. solar energy
Reason: Light (solar radiation) supplies the energy for photosynthesis and thus sets the upper limit on primary production. Nutrients and water frequently act as local limiting factors (e.g., N or P in aquatic systems, water in deserts), but solar energy is the primary energy source driving net primary productivity.
