Explanation:
The correct option is 'd'. The evaluation of Lisfranc (tarsometatarsal) injuries relies on critical radiographic lines. On an AP radiograph, the medial border of the second metatarsal base must form a continuous, unbroken straight line with the medial border of the middle (intermediate) cuneiform. Any step-off or diastasis >2mm indicates a disruption of the Lisfranc ligament complex.
