It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
        
                    
             
        
        
        
Answer: supersaturated
Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature. 
A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated. 
A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.
An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.
A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.
