Question

which of the following statements correctly distinguishes between irritable bowel syndrome (ibs) and inflammatory bowel disease (ibd)? a. ibs is a chronic inflammatory condition, while ibd is a functional digestive disorder b. ibs is caused by infection, while ibd is caused by stress c. ibs is a functional digestive disorder, while ibd is a group of conditions that cause chronic inflammation in the digestive tract d. ibs and ibd are both autoimmune diseases, but they have different symptoms

Explanation:

• Option A: IBS is functional, IBD is inflammatory (A swaps them), so A is wrong.
• Option B: IBS isn't caused by infection, IBD isn't caused by stress (causes are misattributed), so B is wrong.
• Option C: IBS is a functional digestive disorder (no structural damage, related to gut function), IBD (like Crohn’s, UC) causes chronic inflammation in the digestive tract. This matches the definitions.
• Option D: IBS is not an autoimmune disease, IBD has autoimmune components (so D is wrong as it says both are autoimmune).

Answer:

C. IBS is a functional digestive disorder, while IBD is a group of conditions that cause chronic inflammation in the digestive tract
