I’m missing the context — what do you mean by “this oxygen”? (a diagram, a reaction, an image, Earth’s atmosphere, a cell?)
Most likely answer: oxygen is produced by photosynthesis. At the molecular/cellular level O2 is released in the light-dependent reactions of photosynthesis when water is split by the oxygen-evolving complex of Photosystem II in the thylakoid membranes of chloroplasts (and in cyanobacteria). On a global scale most of the O2 in Earth’s atmosphere comes from marine photosynthetic microbes (phytoplankton and cyanobacteria), with plants and algae also contributing.
If you meant a different process (electrolysis, decomposition, a chemical equation in a diagram, or oxygen produced by the lungs), tell me which and I’ll answer specifically.
