What is the epidermis mainly composed of?

Dead cells
Water
Collagen
Keratin

The correct answer is: Dead cells

The epidermis is mainly composed of dead cells that are constantly shedding and being replaced by new skin cells. Water, collagen, and keratin are also important components of the epidermis, but dead cells make up the majority. Water helps to hydrate and moisturize the skin, collagen provides strength and elasticity, and keratin is a protein that forms a protective barrier on the skin's surface. However, these components are not the main composition of the epidermis and do not make up the majority of its structure. Therefore, option A is the best answer.
