Final Answer :
D
Explanation :
Astrocytes, a type of glial cell in the brain, do not directly aid in the regeneration of injured neurons. Their primary roles include supporting neurons, forming the blood-brain barrier, and contributing to the repair and scarring process after central nervous system injury, but they do not facilitate neuronal regeneration.
