Which of the following is the best description of the process shown in the image below?

The process in the image is ( C ) : Water, carbon dioxide and light are inputs while oxygen and glucose are outputs

The process represented in the diagram is photosynthesis because Photosynthesis is the process whereby green plants makes use of water and Carbon dioxide from the atmosphere in the presence of light  to produce its food and also producing oxygen as its by product in the process

Photosynthesis :

H₂0 + CO₂  + light energy >  C₆H₁₂O₆ + O₂

Hence we can conclude that the  process in the image is Water, carbon dioxide and light are inputs while oxygen and glucose are outputs
