B) CO2+2H2O \xrightarrow[{light}]{chlorophyll} CH2O+2H2O+O2
C) 6CO2+6H2O \xrightarrow[{light}]{chlorophyll} C6H12O6+6H2O+6O2
D) 6CO2+12H2O \xrightarrow[{light}]{chlorophyll} C6H12O6+6H2O+6O2

View Answer
C) 6CO2+6H2O \xrightarrow[{light}]{chlorophyll} C6H12O6+6H2O+6O2

Explanation:Correct balanced photosynthesis equation:
