Practice question

Pick C: Retina. Thinking about Peripheral Nervous System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: Retina is the option that correctly names the structure, process, or principle asked for in Peripheral Nervous System. Hence Retina is correct. Treat this as a building block for the rest of Peripheral Nervous System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Retina.
