The right option is; B) oxygen
Oxygen which is denoted as O2 is a product in this chemical reaction.
Energy + 6CO2 + 6H2O → 6O2 + C6H12O6
Photosynthesis is the process by which plants and other photoautotrophs converts carbon dioxide and water to produce glucose (energy) in the presence of sunlight, while oxygen is being released as a byproduct. In this process, 6 molecules of carbon dioxide combine with 6 molecules of water in the presence of sunlight energy to synthesis 1 molecule of glucose and 6 molecules of oxygen.
