Answer: The correct answer is B. 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2
Photosynthesis is a process of synthesis of food in green plants and algae. In this process, energy from sunlight is absorbed by chlorophyll pigment in the presence of CO₂ and H₂O and it is used for the formation of food, which is a carbohydrate ( glucose).
Thus, CO₂ and H₂O are used as reactants and glucose ( C₆H₁₂O₆) is synthesized as a final product of the process along with O₂ ( oxygen).
Option B) is the correct balanced equation for this process.
