The researchers then compared the brain scans and the personality test results. What was one of the results that they found?

A) Extraversion was associated with larger brain tissue volume in the medial orbitofrontal cortex, a brain region that is associated with sensitivity to rewarding stimuli
B) Extraversion was associated with smaller brain tissue volume in the medial orbitofrontal cortex, a brain region that is associated with sensitivity to rewarding stimuli.
C) Extraversion was associated with larger brain tissue volume in the fusiform gyrus, a brain region that is associated with sensitivity to rewarding stimuli.
D) Extraversion was associated with smaller brain tissue volume in the fusiform gyrus, a brain region that is associated with sensitivity to rewarding stimuli.
