Answer:
(B) the nerve connecting the olfactory bulb sends impulses directly to the limbic system
Explanation:
The limbic system is the part of the brain that regulates memory, emotions, and hunger. It is composed by the hypothalamus, the thalamus and the amygdala of the brain. On the other hand, the olfactory bulb is responsible for coding and directing the information that enters through the smell through the olfactory neurons and to discern between the different smells.
Due to the proximity of the olfactory bulb to the limbic system, an associative learning process occurs in which the amygdala and the hippocampus interact; smells are associated with situations such as aversive or reinforcing stimuli, so certain odors provoke positive responses and other negative or aversive responses, directly affecting emotions.
