Correct Answer: A

Rationale: A low-fiber diet is implicated in the development of diverticulosis because it leads to harder stools and increased pressure in the colon. The lack of fiber results in decreased bulk and slower transit time, predisposing individuals to constipation and the formation of diverticula.

High-protein and low-carbohydrate diets do not have a direct association with diverticulosis.
