Answer:

Although the soft-tissue lining of oysters and clams creates pearls, pearl is not a mineral because it is an organic substance. The correct answer is the last one.

Pearls are often considered gemstones; they are a composite of the mineral Aragonite and the organic compound conchiolin, which is a protein, and the combination of both of them is called nacre.
