hey, thank you for replying , bur for C , doesn’t it say that Hydrogen is produced in the cathode? I thought oxygen would get electron and get reduced in cathode .
how come this is the correct answer?

Hi! I typed it wrong O will be oxidized at the anode, and H will be reduced at the cathode, according to the periodic table trend
Sorry for the confusion
