Explanation:

A) The arrow points to the Olfactory Nerve (Cranial Nerve I). It is located at the base of the frontal lobes, associated with the olfactory bulbs (visible in the inferior view of the brain, near the front/midline).
B) The function of the olfactory nerve is to transmit olfactory (smell) sensations from the nasal cavity to the brain. It is the primary nerve for the sense of smell.
C) The sensation (smell) carried by the olfactory nerve is finally received by the Temporal Lobe (specifically, the olfactory cortex, which includes areas like the piriform cortex and parts of the temporal lobe, along with the frontal lobe’s orbitofrontal cortex for smell perception integration).

Answer:

A) Olfactory Nerve (Cranial Nerve I)
B) Transmits olfactory (smell) sensations from the nose to the brain.
C) Temporal Lobe (with involvement of frontal lobe regions for integration)
