**Core Concept**
The femoral ring is an anatomical structure in the femoral canal, which is a passageway through the femoral sheath. The femoral ring is bounded by specific structures that allow for the passage of lymphatic vessels and nerves. Understanding the boundaries of the femoral ring is crucial for identifying femoral hernias.

**Why the Correct Answer is Right**
The femoral ring is bounded by the lacunar ligament (Gimbernat's ligament) anteriorly, the femoral vein medially, and the femoral artery laterally. The femoral ring is also bounded by the pectineal ligament (Cooper's ligament) posteriorly. This arrangement of structures allows for the passage of lymphatic vessels and nerves through the femoral canal.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not mention a structure that bounds the femoral ring.
* **Option B:** This option is incorrect because it is not a structure that bounds the femoral ring; it may be a structure related to the femoral triangle, but it is not relevant to the femoral ring.
* **Option C:** This option is incorrect because it is not a structure that bounds the femoral ring; it may be a structure related to the inguinal canal, but it is not relevant to the femoral ring.

**Clinical Pearl / High-Yield Fact**
When examining a patient for a femoral hernia, it is essential to identify the boundaries of the femoral ring, as a femoral hernia typically protrudes through the femoral ring.
