• A. iliac crest
• B. pubic arch
• C. acetabular notch
• D. obturator foramen

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the anatomical location of the subpubic angle. It is the angle formed by the convergence of the inferior rami of the pubic bones, located at the anterior part of the pelvis.
2. Step 2: Review the options provided: iliac crest, pubic arch, acetabular notch, and obturator foramen. Each term refers to a distinct anatomical structure.
3. Step 3: Clarify the term 'pubic arch.' The pubic arch is formed by the inferior rami of the pubic bones and is synonymous with the subpubic angle. This structure is used to differentiate male and female pelvises based on the angle's width.
4. Step 4: Eliminate incorrect options: The iliac crest is the upper border of the ilium, unrelated to the subpubic angle. The acetabular notch is part of the acetabulum, where the femur articulates. The obturator foramen is a large opening in the pelvis, not an angle.
5. Step 5: Conclude that the correct term for the subpubic angle is the pubic arch, based on anatomical definitions and the elimination of other options.
