There are a number of ways to create oxygen. Two that come to mind use air or water to do so. Air is comprised of oxygen, nitrogen, carbon dioxide, and trace levels of other gases including water vapor. It is possible to separate out these gases and be left with pure oxygen. Many techniques could be used to do this. Water is H2O. Meaning that it is a molecule of hydrogen and oxygen. It is possible to separate water into its components thereby leaving behind these two gases. These then could be considered 2 raw materials as you put it that could be made into pure oxygen. There are others but these would be the two commonest.

Does this question come from a lab that your son did in school? If so then the answer must come from the lab observations. If the teacher used hydrogen peroxide to produce oxygen then the answer is H2O2. It depends on the experiment done. Oxygen is pure O2. Fractional distillation of liquid air is hw it is done commercially, so air.

It's extracted from water by electrolysis. Pure water doesn't conduct electricty so it has a small amount of acid added to it, causing ions to form. Electricty is then passed through it, causing oxygen to be evolved at one electrode.

The raw material used to obtain oxygen is air. Air is 21% oxygen. It can be separated from the other components by fractional distillation.

warming potasium permanganate gives off oxygen, a mixture of hydrogen peroxide and manganese dioxide will also produce oxygen - don't try this at home folks !

if you pass an electrical current through water, you can collect pure hydrogen and oxygen at the cathode and anode.
