Match List - I with List - II:

List 1	List 2
A. Electroencephalography	I. Images of brain by means of magnetic field
B. Computerized Tomography	II. Detecting brain activity through glucose utilization
C. Magnetic Resonance Imaging	III. Brain scanning through X-ray images
D. Positron Emission Tomography	IV. Measuring brain activity through electrodes on scalp

Correct option is D

The correct matching of brain imaging techniques to their descriptions is as follows:
    A. Electro Encephalography (EEG) – IV: EEG measures brain activity through electrodes placed on the scalp, commonly used to study electrical patterns in the brain, such as during sleep or seizures.
    B. Computerized Tomography (CT) – III: CT scans create detailed images of the brain using X-ray technology, commonly used to detect tumors, strokes, or injuries.
    C. Magnetic Resonance Imaging (MRI) – I: MRI uses magnetic fields and radio waves to generate detailed images of the brain's structure and is widely used in diagnosing neurological disorders.
    D. Positron Emission Tomography (PET) – II: PET measures brain activity by detecting glucose metabolism, making it useful for studying brain function and identifying abnormalities like Alzheimer's disease.
