Show answer and explanation
Correct answer: A. Glass ionomer cement

- B. Composites are hydrophobic resins that do not require water and do not release fluoride (unless modified).
- C. Amalgam contains mercury/metal alloy and does not release fluoride.
- D. Zinc oxide-eugenol is a sedative cement, not a fluoride-releasing, water-based glass ionomer.
