Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.

Correct Answer: A

Correct Answer: D

Rationale: Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus, but it commonly affects the small intestine and colon, involving the entire thickness of the bowel wall.

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-fiber diets, on the other hand, promote regular bowel movements and help prevent diverticular disease. High-protein and low-carbohydrate diets do not have a direct association with diverticulosis.
