Answer 1

The correct option is C

Keratin helps waterproof and protect the skin

It is made of flat, scale-like cells called epithelial cells and specialized cells are known as keratinocytes. These cells protect our body and prevent pathogens from penetrating the skin. An important protein called keratin anchors the cells together and to the layer beneath it, the dermis.
