Roger Romeo, Always the Confident and Self-Assured Man-About-Campus, Is Dismayed

Roger Romeo, always the confident and self-assured man-about-campus, is dismayed to find that every time he smells the perfume his first girlfriend wore, he gets tears in his eyes and a lump in his throat. What is the most likely physiological explanation for this involuntary response?

A) The frontal lobe controls motor activity, which is inhibited by smell.
B) The substantia nigra secretes dopamine, which inhibits his corpus striatum, and causes emotional responses (i.e., acting like a "dope") .
C) The mammillary bodies in the hypothalamus produce strong reflexive physical and emotional responses to odors and memories.
D) The temporal lobe evaluates auditory and olfactory input.
E) The comparator function of the cerebellum compares old and new smells.
