If the concentration of potassium chloride is low during electrolysis, why is oxygen produced at the anode instead of chlorine?

Question

I don't understand where the oxygen is from, what the solution and electrolyte are. Any help is greatly appreciated

I think the question just answered it self, since it says that the concentration of #KCl# is low..

Hence most of the chlorine if not all would have been used up in the reaction..

#C = m/v#

And where the oxygen is coming from, perhaps water is used as a solvent or it is contained in the solution..
