Best answer
The correct option is (c) high amplitude, high frequency waves

Best explanation: When a seizure occurs, the EEG shoots, giving a high frequency high, amplitude output. This is because, during a seizure, the brain activity becomes extremely high that the signals are generated faster than they are processed and dispersed. Since the brain is not able to send out signals fast enough or rather the body is not able to act on the signals fast enough, shaking, trembling or other physical outlets may happen.
