Nerves in the peripheral nervous system have the capacity to regenerate, which means that if the toe is not too damaged, there is a good chance that it can be reattached to Sylvester's foot. Nerves in the central nervous system do not have the same capacity for regeneration, which rules out option B. Option D is incorrect because the autonomic nervous system controls involuntary actions such as heart rate and digestion, and has no role in controlling the movement of limbs or fingers. Option A is also incorrect because while nerves in the peripheral nervous system may not regenerate as quickly or completely as other tissues, they can still regenerate to some extent.
