Complete pelvis describes which anatomy?

• A. A pelvis with a full pelvic girdle with two pelvic spines
• B. A pelvis with a single spine
• C. No pelvic girdle
• D. An oval nub for a girdle

Answer: (C)

In this context, the term complete pelvis is tied to whether the pelvic girdle is present or not. A complete pelvis is described as lacking the pelvic girdle, so the anatomy would have no hip bones connecting the hind limbs to the spine. The other options describe varying amounts of girdle structure—two spines, a single spine, or a small nub—none of which match the idea of a pelvis described without a girdle. So the description that fits best is no pelvic girdle.
