**Option B:** Similarly, this option is incorrect as it doesn't match the usual branching pattern of major arteries related to the gastrointestinal system.
**Option C:** This choice is also incorrect because it doesn't correspond to the known branching patterns of major arteries.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the **celiac trunk** and its branches supply blood to the foregut structures, including the stomach, liver, and pancreas.
