Explanation

The passage directly states: "the peripheral nervous system consisting of cranial nerves arising from the brain and spinal nerves arising from the spinal cord." Option A describes the CNS, not PNS. Options C and D are incorrect. For MCQs, briefly state the correct option letter and a one-line justification — examiners award the mark for the correct choice supported by a reason.
