Explanation:
The correct option is 'd'. The Kocher-Langenbeck (posterior) approach is the standard workhorse for visualizing and treating fractures of the posterior wall and posterior column of the acetabulum. The patient is placed prone or lateral, and the sciatic nerve must be carefully protected. The ilioinguinal and modified Stoppa approaches are utilized for anterior column and anterior wall injuries.
