Solution

The correct option is A Pearl oyster and mussel
Pinctada is a genus of pearl oyster, saltwater clams, marine bivalve molluscs in the family Pteridae. These oysters have a strong inner shell layer composed of nacre, also known as 'mother of peal'. All species within the genus produce pearls. The various species of Pinctada produce maximum different sizes and colours of pearls, depending on the size of the species and the natural colour of the nacre inside the shell. Mussel is the common name used for members of several families of clams or bivalve molluscs, from saltwater and freshwater habitats.
