Option B is correct answer.
The process of photosynthesis involves the splitting of water molecules.These water molecules provide free electrons to slipt the carbon from the carbon dioxide and then the final byproduct of this process is glucose and oxygen.
The part of the light reaction of photosynthesis is the splitting of water molecules (Option B). This process helps generate oxygen and replaces lost electrons in chlorophyll. These reactions are essential for converting light energy into chemical energy in the form of ATP and NADPH.
