Cells that can conduct, but not replicate
A
neurons
B
glia/neuroglia
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Glial cells are known to be capable of mitosis. By contrast, scientific understanding of whether neurons are permanently post-mitotic, or capable of mitosis, is still developing. In the past, glia had been considered to lack certain features of neurons.

Detailed explanation-2: -Glial (Neuroglial) cells do not conduct nerve impulses, but, instead, support, nourish, and protect the neurons. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.

Detailed explanation-3: -Unlike neurons, glial cells cannot fire action potentials to communicate messages, but that does not mean they are inactive. Glia communicate to each other and to neurons using chemical signals, and can even respond to many of the same chemicals that neurons can, such as ions and neurotransmitters.
