Solution

The correct option is A Hydrolysis of water
During this process, the electrons in water are removed and passed to the reaction center chlorophyll. The associated hydrogen ions are released from the water molecule, and after two water molecules are thus split, the oxygen atoms join to form molecular oxygen (O ₂ ), a waste product of photosynthesis.

So, the correct option is 'Hydrolysis of water'.
