**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not accurately describe the inlet's formation.
**Option B:** Incorrect as it is not a correct anatomical description.
**Option D:** Incorrect due to inaccurate anatomical representation.
**Clinical Pearl / High-Yield Fact**
