Correct Answer: A. Polydioxanone
Explanation: Polydioxanone (PDS) is an absorbable suture that lasts 180 days and is good for high tension areas such as the leg. Monofilament sutures such as poliglecaprone 25 and glycomer 631 work, but not as well in terms of duration of tensile strength for high tension areas.
