Elizabeth Always Has to Check That the Stove and Lights

Elizabeth always has to check that the stove and lights are off at least five times before she could leave for work in the morning. If we were able to track her brain activity when this compulsive behaviour occurs, the

A) prefrontal caudate-thalamus circuit would be activated (orbitofrontal and medial prefrontal cortex, cingulate gyrus) .
B) cerebellum would be activated.
C) mesolimbic pathway (ventral tegmental area, ventral striatum, basal ganglia) .
D) hypothalamus.
E) amygdala.
