**Core Concept**
The celiac trunk is a major artery that arises from the abdominal aorta and supplies blood to the upper abdominal organs. It is a key structure in the abdominal vascular anatomy, and its branches are essential for the blood supply of various organs.

**Why the Correct Answer is Right**
The celiac trunk has three main direct branches: the left gastric artery, the splenic artery, and the common hepatic artery. These branches arise directly from the celiac trunk and supply blood to the stomach, spleen, and liver, respectively. The left gastric artery supplies the stomach, the splenic artery supplies the spleen and pancreas, and the common hepatic artery supplies the liver and gallbladder.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a direct branch of the celiac trunk. The superior mesenteric artery is a separate branch that arises from the abdominal aorta, just below the celiac trunk.
**Option B:** This option is incorrect because it is not a direct branch of the celiac trunk. The inferior mesenteric artery is a separate branch that arises from the abdominal aorta, below the superior mesenteric artery.
**Option C:** This option is incorrect because it is not a direct branch of the celiac trunk. The renal arteries arise from the abdominal aorta, above the celiac trunk, and supply blood to the kidneys.

**Clinical Pearl / High-Yield Fact**
The celiac trunk is a key landmark in abdominal surgery and is often used as a reference point for identifying other vascular structures in the region. A thorough understanding of the celiac trunk and its branches is essential for surgeons and radiologists working in this area.

**Correct Answer: C. Common hepatic artery. Common hepatic artery is a direct branch of the celiac trunk.**
