Solution

The correct option is C Shell and mantle
When a foreign particle enters between the shell and mantle of the animal, a secretion comes out from mother-of-pearl of mantle. This secretion surrounds the foreign particle which later becomes hard and glossy. This hard and glossy substance is known as pearl. Pearl is formed outside the mantle but inside the shell of mollusk.
Thus, the correct answer is option C.
