Xerostomia is best described as which symptom?

Explanation:
Xerostomia is the sensation of a dry mouth due to reduced saliva production. Saliva keeps the mouth lubricated, aids in swallowing and tasting, and protects teeth from decay and infections. When saliva is diminished, the oral tissues feel dry, possibly sticky or gritty, especially when speaking or swallowing. This dry mouth description is the best fit for xerostomia. The other options—dry skin, headache, and nausea—do not describe xerostomia and relate to different conditions or systems.
