During photosynthesis, plants absorb water nd carbon, after Absorption, the water molecules disassembled and converted into sugar and oxygen.

O2 is release in the form of water vapour.
In photo synthesis the main product is sugar along oxygen.

Photosynthesis occurs in the presence of water. Therefore water dissociates to form oxygen atoms thereby releasing oxygen.

Ruben's experiments using 'heavy water', H218O, to yield 18O2 gas had shown that the oxygen gas produced in photosynthesis comes from water.

Ref : Rubin , Hassid and kamen who experimentally proved that oxygen liberated during photosynthesis comes from water.
Actually, the reaction is;
6 CO2 + 12 H2O - C6 H12 O6 + 6 O2 + 6 H2O.
Actually, the reaction is;
6 CO2 + 12 H2O - C6 H12 O6 + 6 O2 + 6 H2O.

Generally, in the light phase step-2 photolysis that means hill's reaction takes place in that is by taking energy from sun-light water molecule splits into hydrogen and hydroxyl ions in that hydroxyl ions further react and lastly forms oxygen and water. So it is possible guys.

Water gets split into H ions and O atom and release electron as well, so the oxygen comes from water.
