**Core Concept**
During a hysterectomy and oophorectomy, identification and ligation of the uterine and ovarian vessels are crucial to prevent excessive blood loss. The uterine arteries and ovarian arteries are key vessels that need to be secured. These vessels run within specific ligaments that support the uterus and ovaries.

**Why the Correct Answer is Right**
The uterine arteries run within the **round ligament of the uterus** and the ovarian arteries run within the **suspensory ligament of the ovary** (also known as the infundibulopelvic ligament). The round ligament of the uterus is a fibromuscular structure that connects the uterus to the labia majora, while the suspensory ligament of the ovary suspends the ovary from the pelvic wall. The round ligament contains the uterine artery, while the suspensory ligament contains the ovarian artery. Securing these vessels within these ligaments is essential during a hysterectomy and oophorectomy.

**Why Each Wrong Option is Incorrect**
**Option A:** The broad ligament of the uterus does not contain the uterine or ovarian arteries. It is a fold of peritoneum that supports the uterus and contains the uterine tubes, round ligament, and other structures.

**Option C:** The round ligament of the uterus contains the uterine artery, not the ovarian artery, which runs within the suspensory ligament of the ovary.

**Option D:** The suspensory ligament of the ovary contains the ovarian artery, not the uterine artery, which runs within the round ligament of the uterus.

**Clinical Pearl / High-Yield Fact**
It is essential to identify and ligate the uterine and ovarian vessels during a hysterectomy and oophorectomy to prevent excessive blood loss. This can be done by carefully dissecting the round ligament of the uterus and the suspensory ligament of the ovary to locate the uterine and ovarian arteries.

**✓ Correct Answer: B. Broad and suspensory**
