Answer: D: 6th decade 
Explanation: GUs tend to occur later in life than duodenal lesions, with a peak incidence repoed in the sixth decade. More than one half of GUs occur in males and are less common than DUs, perhaps due to the higher likelihood of GUs being silent and presenting only after a complication develops.
