The method used for recording the brain's metabolic and synaptic activity by measuring the BOLD signal from the brain is C) fMRI.

Here's a step-by-step explanation:

1. The BOLD signal, or Blood Oxygen Level Dependent signal, is a method used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which correspond with the expected neural activity.

2. fMRI measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.

3. The primary form of fMRI uses the BOLD contrast, a type of signal that is strongly, but not exclusively, sensitive to changes in blood oxygenation and flow.

4. Therefore, when the BOLD signal is measured, it can give an indication of the metabolic and synaptic activity in the brain.

5. So, the answer is C) fMRI. Neither MEG (Magnetoencephalography), EEG (Electroencephalography), nor TMS (Transcranial Magnetic Stimulation) use the BOLD signal to measure brain activity.
