Step 1
: Identify the correct chemical reaction for photosynthesis.

Photosynthesis is the process by which green plants convert carbon dioxide, water, and light energy into glucose and oxygen. The correct reaction should have carbon dioxide (CO2), water (H^2O), and light energy (not explicitly shown in the options) as reactants, and glucose (C^6H^12O6) and oxygen (O2) as products.

Step 2
: Examine the given options to find the correct reaction.

A. 6H^2O + 6O^2 → C^6H^12O^6 + 6CO^2 (Water and oxygen are reactants, which is incorrect.) B. C^6H^12O^6 + 6O^2 → 6CO^2 + 6H^2O (Glucose and oxygen are reactants, which is incorrect.) C. 6CO^2 + 6H^2O → C^6H^12O^6 + 6O^2 (This is the correct reaction.) D. 6CO^2 + 6O^2 → C^6H^12O^6 + 6H^2O (Oxygen is a reactant, which is incorrect.) E. C^6H^12O^6 + 6CO^2 → 6O^2 + 6H^2O (Glucose and carbon dioxide are reactants, which is incorrect.)

Final Answer

The correct equation representing photosynthesis is option C: 6CO^2 + 6H^2O → C^6H^12O^6 + 6O^2.
