D Correct answer
Explanation

The hydrogen ions also called protons, are made available by splitting up of water. Non-cyclic photophosphorylation needs a constant supply of water molecules. The net result of non-cyclic phosphorylation is the formation of oxygen, NADPH and ATP molecules. Oxygen is produced, as a waste product of photosynthesis.
