The answer to this question would be: Chlorophyll absorbs the light needed for photosynthesis
The equation for photosynthesis would be:
6CO2 + 6H2O ------> C6H12O6 + 6O2
In the equation, it is clear that the carbon dioxide and water will create glucose, oxygen. In this process, the chlorophyll is catching the energy that provided by sunlight. That means the statement "Chlorophyll Combines with water to form oxygen " is wrong.
