The correct answer is: Gastroduodenal

For a good understanding of this question, take a look at Netter Plate 290. The gastroduodenal artery is a branch of the common hepatic artery; it descends behind the first part of the duodenum. So, if an ulcer destroyed the posterior wall of the duodenum, gastric juices could escape and destroy the gastroduodenal artery. The common hepatic artery is a branch of the celiac trunk found superior to the duodenum. The left gastric artery is a branch of the celiac trunk which supplies the left side of the lesser curvature of the stomach. The proper hepatic artery is a branch of the common hepatic artery; it travels superiorly from the common hepatic artery to give off the right, middle, and left hepatic arteries. Finally, the superior mesenteric artery originates from the aorta at the bottom of the L1 level, posterior to the pancreas. It travels over the 3rd part of the duodenum and supplies the intestines, up to the last third of the transverse colon.
