The light-dependent reactions of photosynthesis involve the splitting of water molecules in a process called photolysis. This process is necessary to release oxygen and to produce the hydrogen ions needed for the production of ATP and NADPH.

To produce one molecule of oxygen (O2), two molecules of water (H2O) are needed. This is because each water molecule provides one oxygen atom, and an oxygen molecule is made up of two oxygen atoms.

Therefore, to produce two molecules of oxygen, four molecules of water are needed. So, the answer is C. 4.
