E) CT scan

Accepted Answer

An electroencephalogram (EEG) is a printed record of the brain's electrical activity over a period of time, typically measured using electrodes placed on the scalp. An electrocardiogram (ECG) measures the electrical activity of the heart, while X-rays, MRI, and CT scans are imaging techniques that provide visual information about the body's structures.
