C Correct answer
Explanation

Oysters are commercially cultivated primarily for pearl production. When an irritant enters the oyster's shell, the mollusk secretes layers of nacre (mother-of-pearl) around it, forming a pearl. This process is utilized in pearl farming through deliberate implantation. Oysters are also valued for food, but pearl cultivation is the primary commercial focus.
