Correct answer: E — EEG is not routinely required; diagnosis rests on the prescribed clinical brainstem tests, clinically

The best answer is “EEG is not routinely required; diagnosis rests on the prescribed clinical brainstem tests, clinically”. UK neurological criteria are based on strict prerequisites and repeated clinical brainstem testing; ancillary investigations do not repair invalid prerequisites. “Electrocerebral silence is mandatory in every UK assessment” remains a plausible alternative in a different presentation, but it does not fit the decisive finding or management threshold here. “A normal EEG excludes death by neurological criteria even when brainstem tests are absent” remains a plausible alternative in a different presentation, but it does not fit the decisive finding or management threshold here. “EEG can replace exclusion of sedative drug effects” remains a plausible alternative in a different presentation, but it does not fit the decisive finding or management threshold here. “One clinician may use EEG alone without repeating the clinical assessment” remains a plausible alternative in a different presentation, but it does not fit the decisive finding or management threshold here.
