Explanation:
B. Duodenal ulcer
The patient's symptoms of epigastric abdominal pain that occurs a few hours after eating, is relieved by eating, and is associated with smoking are characteristic of a duodenal ulcer. The pain in duodenal ulcers often occurs when the stomach is empty and is relieved by food intake.
In contrast, gastric ulcers tend to cause pain shortly after eating and are often associated with nausea or vomiting. The patient's presentation is more suggestive of a duodenal ulcer.
