All of the options provided can be used to visualize ongoing biological activity of a living brain, but each has its own strengths and weaknesses.

Electroencephalography (EEG) measures electrical activity in the brain and is widely used because of its high temporal resolution (meaning it can detect changes in brain activity quickly). However, EEG has lower spatial resolution and is limited in its ability to locate exactly where brain activity is occurring.

Functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) both provide better spatial resolution, allowing researchers to see activity in specific areas of the brain, but they have lower temporal resolution. fMRI is particularly useful for identifying changes in blood flow, and PET scans can provide more detailed information about metabolic activity in the brain.

Therefore, to get a comprehensive understanding of the ongoing biological activity of a living brain, it is best to use a combination of these techniques, which is why the answer is D.
