What basin-like structure is formed by the two hip bones, the sacrum, and coccyx?

• A. Face
• B. Pelvis
• C. Abdomen
• D. Trunk or Torso

Answer: (B)

This item tests your knowledge of the basin-shaped bony framework that anchors the lower body. The two hip bones together with the sacrum and coccyx form the pelvis, also called the pelvic girdle. This ring-like structure supports the pelvic organs and provides attachments for the lower limbs. The face is part of the skull, not a pelvic ring; the abdomen is the belly region containing organs but not a distinct bony basin; the trunk or torso refers to the central body region including the chest and abdomen, not specifically the basin formed by the pelvic bones. Therefore, the correct answer is pelvis.
