**Core Concept**
The **broad ligament** is a fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis, providing support and containing various structures. It is essential to understand the anatomy of the broad ligament to identify its contents. The broad ligament contains the **ovarian ligament**, **round ligament of the uterus**, and **ligamentum teres uteri**, among other structures.

**Why the Correct Answer is Right**
Since the question is incomplete, let's discuss the general contents of the broad ligament. The broad ligament contains the **ovarian ligament**, which connects the ovary to the uterus, and the **round ligament of the uterus**, which extends from the uterus to the labia majora. Other contents include blood vessels, nerves, and the **ligamentum teres uteri**.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, it's challenging to provide a detailed explanation.
**Option B:** Similarly, without the option, it's difficult to explain why it's incorrect.
**Option C:** Assuming this option might be related to a structure not contained within the broad ligament, it could be incorrect due to the broad ligament's specific anatomy.
**Option D:** This option might be incorrect if it represents a structure that is indeed contained within the broad ligament.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the broad ligament supports the uterus and contains various ligaments and vessels. Knowing its contents is crucial for understanding pelvic anatomy and pathology.

**Correct Answer:** Correct Answer: D. Ovarian artery
