Answer 1

The correct option is B

Insects

The correct option is B

3. Numerous insect species eat clothing. Female moths frequently choose clothes composed of keratin-containing textiles like cashmere, silk, and wool.
4. Cotton and synthetic fabrics are not eaten by moth larvae unless they are mixed with animal fiber because they lack keratin,
5. The most prevalent cause of clothing destruction is the clothes moth (Tineola bisselliella) larva.
