**Core Concept**
The supports of the uterus refer to the ligaments, fasciae, and muscles that provide stability and maintain the position of the uterus within the pelvis. The uterosacral and round ligaments play a crucial role in supporting the uterus, particularly during pregnancy and childbirth.

**Why the Correct Answer is Right**
The correct answer should be a structure that is not considered a primary support of the uterus. The uterosacral ligaments connect the cervix to the sacrum, providing lateral support to the uterus. The round ligaments of the uterus extend from the uterine horns to the labia majora, offering anterior and posterior support. In contrast, the correct answer is not a primary support of the uterus.

**Why Each Wrong Option is Incorrect**
**Option A:** The uterosacral ligaments are indeed a primary support of the uterus, connecting the cervix to the sacrum and providing lateral stability.

**Option B:** The round ligaments of the uterus are also a primary support, extending from the uterine horns to the labia majora and offering anterior and posterior support.

**Option C:** The cardinal ligaments, including the uterosacral and transverse cervical ligaments, are considered primary supports of the uterus, providing lateral and anterior support.

**Clinical Pearl / High-Yield Fact**
Remember that the round ligaments of the uterus are not just passive supports but also play a role in maintaining the anteverted position of the uterus.

**Correct Answer: D.**
