Explanation:

• Option A: Stress typically increases gastrin (not diminishes) related to GI issues, so A is wrong.
• Option B: Gastrin elevation from stress can increase stomach acid, leading to ulcers, which matches GI system effects.
• Option C: Cortisol elevation from stress relates to overeating, but this is more about metabolism/appetite, not direct GI system (like ulcers/constipation).
• Option D: Stress increases cortisol (not diminishes), so D is wrong.
