The answer is: B. Pearl
Honey, coral, wax, and resin are all natural substances produced by living organisms. Pearls, on the other hand, are not produced by living organisms. They are formed when an irritant, such as a parasite or a piece of sand, gets inside an oyster’s shell. The oyster coats the irritant with layers of nacre, a substance that is made up of calcium carbonate and proteins. Over time, the layers of nacre build up and form a pearl.
Honey is a sweet, sticky substance produced by honey bees from the nectar of flowers. It is used as a sweetener and as a preservative.
Coral is a hard, calcareous substance produced by coral polyps, which are small, marine animals. Coral reefs are formed by the accumulation of coral skeletons.
Wax is a solid or semi-solid substance produced by plants or animals. It is used in candles, cosmetics, and other products.
Resin is a sticky, flammable substance produced by plants. It is used in varnishes, adhesives, and other products.
