    The correct answer is D) Keratin.

    Explanation:

    Keratin is a fibrous protein produced by epithelial cells called keratinocytes. They form the tough structural parts of the body like nails, claws, hairs, horns, etc, which are resistant to abrasion, wear and tear. Melanin is a protein pigment produced by cells called melanocytes. Skin gets coloured due to this pigment. The epidermis of the skin is divided into five layers: Stratum germinativum, Stratum spinosum, Stratum granulosum, Stratum lucidum and Stratum corneum. The Stratum germinativum is the deepest layer found in the epidermis and is made up of a single cuboidal or columnar epithelial cell layer. Dermal papilla is formed by the finger-like intrusion of the dermis layer of the skin into the epidermis. It is mainly responsible for providing oxygen and nutrients to the lower layers of the epidermis.
