Correct Answer: C. Four

Explanation

The pelvis consists of four bones.
✅ Correct answer: C. Four

Explanation:

The bony pelvis is formed by four bones:

   • Each hip bone is formed by the fusion of:
     • Ilium
     • Ischium
     • Pubis
2. Sacrum – formed by the fusion of five sacral vertebrae
3. Coccyx – formed by the fusion of usually four coccygeal vertebrae

Summary:

• Hip bones → 2
• Sacrum → 1
• Coccyx → 1

👉 Total = 4 bones
