Answer:
D) PROTIENS
Explanation:
The silkworms are fed with mulberry leaves, and after the fourth molt, they climb a twig placed near them and spin their silken cocoons. The silk is a continuous filament comprising fibroin protein, secreted from two salivary glands in the head of each worm, and a gum called sericin, which cements the filaments.
