Transcranial magnetic stimulation is used to temporarily disrupt the function of a brain area.  

Option B

Explanation:

A "non-invasive brain stimulation technique" using a strong electromagnet to temporarily disrupt the function of a brain area is called Transcranial magnetic stimulation. An "electric pulse generator" is connected to "scalp" in order to create a magnetic field. "Transcranial magnetic stimulation" is helpful for mental disorders and depression, although research is still going on. Although, TMS has several therapeutic properties, sometimes it can lead to adverse health effects too like fainting, seizures, hypomania, memory loss, and many more.
