unmyelinated axons and neuron cell bodies in CNS
A
white matter
B
gray matter
C
neurilemma
D
neurofibrils
Explanation: 

Detailed explanation-1: -Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies. In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin. The grey matter serves to process information in the brain.

Detailed explanation-2: -Grey matter consists of neuronal cell bodies and their dendrites. The dendrites are short protrusions (like little fingers) that communicate with neurons close by.

Detailed explanation-3: -Gray matter is a major component of the CNS, it refers to un-myelinated neurons and other cells of the central nervous system such as glial cells and dendrites. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord. Gray matter contains most of the brain’s neuronal cell bodies.
