Correct: B — normally the peak systolic velocity is expected to be higher at the ankle than in the arm. Peak systolic velocity rises progressively down the arterial tree as the vessels taper, so the tibial arteries show higher velocities than the brachial artery — which is why option A is inverted. Occlusive disease *reduces* the velocity distal to the lesion (option C), and tibial velocities remain interpretable in peripheral arterial disease (option D).
