Option 1: Hydrolysis of carbohydrates
Option 2: Photolysis of water
Option 3: Reduction of CO2
Option 4: Breakdown of chlorophyll

Oxygen is created as a consequence of photosynthesis's light-dependent processes, particularly photolysis, in which water molecules are split to liberate oxygen, electrons, and protons. The reaction involved in photosynthesis is 6CO 2 +6H 2 O----sunlight----> C 6 H 12 O 6 + 6O 2 .
