- A. Correct. Amitriptyline (a tricyclic antidepressant) has strong anticholinergic effects → drug-induced xerostomia.
- B. Sjögren is possible but the chart points directly to a known xerostomic drug.
- C. Dehydration is not indicated.
- D. Diabetes can cause dry mouth but the listed TCA is the obvious cause.
