A 35-Year-Old Man Visits the Emergency Room with Recurrent Stomach

A 35-year-old man visits the emergency room with recurrent stomach discomfort. He was involved in a full-speed collision with another player during a soccer game yesterday. He was experiencing generalized abdomen pain at the time but did not seek medical attention until this morning, when the agony seemed to grow. A CT scan of the abdomen is obtained as part of the patient's examination, as illustrated in the image below. It is found that his damage affects an organ that is primarily fed by a foregut artery, despite the fact that the organ itself is not a foregut derivation. Which of the following organs in this patient is most likely to be injured?

A) A
B) B
C) C
D) D
