D Correct answer
Explanation

The human pelvis is indeed remarkable for all these features: it has a deep concavity (the pelvic cavity) to protect abdominal organs, it is broad (for upright walking and birth canal), and the ilium is expanded (forming the familiar hip shape). These adaptations are crucial for bipedal locomotion and parturition.
