Best answer
Right answer is (a) EOG

The best explanation: EOG stands for electrooculogram and it the signal that is taken from the eye. The occipital lobe is the center for eye movements so if an EEG is being taken from the Occipital Lobe, the incoming signals from the eyes (EOG) will act as noise to them.
