Answer:
C. Bulb
Explanation:
Our sense of smell is totally dependent on the olfactory bulb. That's because we can smell things, it is necessary that the chemical substances responsible for the fullness are transported by air to our nose, which captures them and takes them to the responsible cells for receiving electrical signals that take these signals to the glomeruli where the olfactory bulb is located, which is the primary olfactory area of our brain.
