Pearls are harvested from

Correct answer: Oyster

Explanation: ✅ Correct Answer: D) Oyster 📚 Explanation: Pearls are beautiful, natural gemstones that are harvested from certain species of marine and freshwater mollusks, primarily oysters. They are formed as a defensive reaction when a tiny foreign irritant becomes trapped inside the mollusk's shell. The animal secretes layers of a crystalline substance called nacre around the irritant over several years, creating a smooth pearl. Cultured pearl farming has become a major commercial industry in coastal regions.
