Answer:
b. have names that indicate the location of the initiation and termination of the nerve impulses
Explanation:
The sensory and motor tracts are sets of nerve fibers that run inside the central nervous system; more precisely within the spinal cord and they are named according to the path their fibers have, that is, we will call them indicating from where they begin to where they arrive.
For example, the spinothalamic tract is a sensory tract that carries the sense of touch and pressure from the spinal cord to the thalamus.
On the other hand, corticospinal tracts are linked to isolated and specialized voluntary movements (especially from the distal part of the limbs) and descend from the cerebral cortex to the spinal cord.
As for the other options, I can say that they are incorrect because the tracts do not differ to the right and left of the cord in sensory and motor. Also, the tracts are located in the white substance not in the gray.
