Concept:The sense of smell is perceived when the olfactory lobes of the brain receive and interpret signals sent from the nose.
Explanation:The accident affected the skull but not the nose, so the nasal receptors themselves were not damaged.
A loss of smell with an undamaged nose means the olfactory pathway or its brain centre has been injured.
The olfactory lobes are the brain regions responsible for processing smell sensations.
A skull injury can damage these lobes directly, causing loss of the sense of smell.
The passage from the nose to the brain and the part of the skull near the nose are less likely, because the skull was affected and the brain area that detects smell is the olfactory lobe.
Thus, the accident must have damaged the olfactory lobes of the brain.
Answer:B. olfactory lobes of the brain
