All of the following signs confirm the brain death except

(A) Hypothermia > Brain death is present when there is irreversible loss of all brain function, both brain-stem function and cortical (hemisphere) function.> Brain death criteria -- Loss of brainstem function & Absent cranial nerve reflexes - Pupillary light reflex; Corneal reflex; Oculo vestibular reflex (cold caloric test; No gag reflex)> Absent respiratory brain stem reflexes is done by Apnea test: Loss of cortical function (No spontaneous movement; no response to external stimuli); Irreversibility> Brain death is present when there is irreversible loss of brain function (criteria ? loss of brainstem function) absent cranial nerve reflexes, pupillary light reflex, corneal reflex, oculo vestibular reflex.
