Final answer:
An EEG is evidence of clinical death when there is no electrical activity in the brain.
Step-by-step explanation:
The correct answer is Arrhythmia. An electroencephalogram (EEG) is a test that measures the electrical activity of the brain, not the heart. It is used to diagnose conditions such as seizure disorders, sleep disorders, and brain abnormalities. Clinical death refers to a state where the vital signs (heart rate, breathing, and brain activity) have ceased, indicating the absence of any electrical activity in the brain. In this state, there would be no brainwaves detected on the EEG.
