a) somatosensory cortex
b) occipital lobe
c) parietal lobe
d) orbitofrontal cortex

The correct answer is option d) "orbitofrontal cortex".

Explanation:

The orbitofrontal cortex (OFC) is the region of the brain responsible of the cognitive process of decision-making. The OFC is involved in the senses of award and remorse based on the results of decision making actions. In this case Jerome exhibits impulsive behavior that lead him to break a man's nose for no reason and had no remorse for doing so. It is likely that Jerome has a tumor in the OFC, which affects his decision making judgement and his feeling of right and wrong.
