Hair is made of the same fibrous protein as which of the following?

• A. Skin
• B. Fibers
• C. Nails
• D. Muscle

Answer: (C)

Hair is primarily composed of a protein called keratin, which is a fibrous protein also found in nails. Both hair and nails serve protective functions in the body, with keratin providing strength and resilience. This similarity in composition is significant in understanding the structure and health of these tissues, as they share similar properties and care needs. Comparatively, while skin does contain keratin, it is not made up in the same fibrous structure as hair and nails. The muscle tissue is composed of entirely different proteins such as actin and myosin, which serve to facilitate movement and contraction. Similarly, the term "fibers" is too vague and does not refer specifically to keratin or any protein directly related to hair formation. Thus, the connection between hair and nails through keratin is what makes the choice regarding nails the correct one.
