A nurse is caring for a client who has Ulcerative Colitis and is teaching the client about a common link with Crohn's disease. Which of the following Information should the nurse include?

A. Both manifest fistula formation: Fistula formation is characteristic of Crohn’s disease due to transmural inflammation, which affects all layers of the intestinal wall. Ulcerative colitis typically involves only the mucosal and submucosal layers, making fistulas uncommon. B. Both begin in the rectum: Ulcerative colitis usually starts in the rectum and may extend proximally in a continuous pattern. Crohn’s disease can affect any part of the gastrointestinal tract from mouth to anus, often in a patchy, segmental distribution. C. Both require frequent surgery: While surgical intervention may be necessary in both diseases for complications, the frequency differs. Ulcerative colitis may require colectomy in severe cases, whereas Crohn’s disease often requires surgery for obstruction or fistula management. D. Both attack the digestive tract: Both ulcerative colitis and Crohn’s disease are types of inflammatory bowel disease (IBD) characterized by chronic inflammation of the gastrointestinal tract. Although the pattern, location, and depth of inflammation differ, the shared pathophysiology involves immune-mediated attacks on the digestive tract.
