A. Medulla B. Cuticle C. Cortex D. Scale
Explanation: The outermost layer of hair is called the cuticle. The cuticle is composed of overlapping scales or cells that help to protect the hair shaft from damage and provide a barrier against external elements such as water and chemicals. The scales of the cuticle are formed from a protein called keratin and are arranged in a shingled pattern that helps to keep the hair shaft smooth and shiny. The cuticle also plays a role in determining the texture of the hair, as the size and shape of the scales can vary between different hair types.
