Answer 1

A. Upper part of the nasal passages

Step-by-step explanation:

Olfactory receptors are specialized sensory cells that detect odors and send signals to the brain. They are located in the olfactory epithelium, a thin layer of tissue that covers the roof of the nasal cavity. The olfactory receptors are exposed to the air that enters the nose, and they bind to molecules that carry different smells.
