Can anyone explain all of the choices and where we see each option? Thank you if you can! I have finished MTB 2/3 and UW, but this info was not there. So, I need doctors to explain me...

A 42-*year*-old man is brought to the physician by his wife because of a 2*month history of staring spells that last 1 to 2 minutes each. During episodes, he also smacks his lips and picks at his shirt collar. Four years ago, he was comatose for 2 weeks after sustaining a head injury in a motorcycle collision; he required 6 months of rehabilitation. He reports that over the past year, he has had intermittent episodes of smelling burnt rubber; episodes occur approximately every 2 weeks. He also hears an intense hissing sound during these episodes. Examination shows no abnormalities. Which of the following is the most likely finding on EEG?

A) Burst*-suppression pattern
B) Diffuse 3*Hz spike and slow wave activity
C) Focal spikes localized to the temporal lobe
D) Hypsarrhythmia
E) Periodic lateralized epileptiform discharges
F) Polyspike and slow wave activity
G) Triphasic waves
