After damage to the axon of a cell,the following sequence (A to E)occurs in the peripheral nervous system (PNS).However,in the CNS,the last step is usually:

A)Degeneration of the distal axon.
B)Chromatolysis in the cell body.
C)Sprouting of new branches.
D)Axon regrowth along the original pathway.
E)Reinnervation of the target.
