Answer (click for answer)
The correct answer is (5) LFCN. Similar to the situation of Ant ICBG harvesting, the LFCN lies just medial to the AntSup Iliac Spine (definitely within the incision for an ilioinguinal approach to the acetabulum) and is at significant risk for injury, and possibly subsequent Meralgia Paresthetica. The nerve must be identified and retracted without significant tension to avoid the aforemention complications.
