Answer: rTMS
rTMS uses magnets to stimulate the areas of the brain.
EEG uses metal discs which are attached to the scalp of the person, but these don’t provide any energy or input to the brain. So it is an incorrect answer.
EMDR uses movement of eyes to detect any symptom of trauma. Again, incorrect answer.
REBT is a kind of a psychological therapy, so it doesn’t use any device or instrument. So, it is a wrong answer.
