A
fMRI & MRI
B
PET & CT
C
EEG & MEG
D
PET & MEG
Explanation: 

Detailed explanation-1: -MRIs and fMRIs are similar technologies. Their primary difference lies in their purpose: MRIs create a picture of the body’s interior structures, while fMRIs record metabolic activity over time. Whereas MRIs are utilized with various parts of the body, including the brain, fMRIs focus solely on the brain.

Detailed explanation-2: -fMRI is used to evaluate subtle regional blood flow changes in brain cortex that occur during patient performance of specific tasks while inside the bore of a high-field MRI scanner (generally, at a field strength of 3 Tesla).

Detailed explanation-3: -Computed tomography (CT) scans are oblique X-ray slices that show the density of brain structures. Magnetic resonance imaging (MRI) uses changes in electrically charged molecules in a magnetic field to form images of the brain.

Detailed explanation-4: -Commonly used brain imaging techniques are: functional magnetic resonance imaging (fMRI) computerized tomography (CT)
