Verified step by step guidance

Step 1: Understand the context of the question. The problem is asking for the primary structural protein found in human hair. This requires knowledge of protein functions and their roles in the human body.

Step 2: Review the options provided: Myosin, Keratin, Elastin, and Collagen. Each of these proteins has distinct functions and structural roles in the body.

Step 3: Recall the function of Keratin. Keratin is a fibrous structural protein that is a key component of hair, nails, and the outer layer of skin. It provides strength and resilience to these tissues.

Step 4: Compare Keratin to the other options: Myosin is involved in muscle contraction, Elastin provides elasticity to tissues like skin and blood vessels, and Collagen is a major structural protein in connective tissues such as tendons and cartilage.

Step 5: Conclude that Keratin is the correct answer because it is specifically the primary structural protein in human hair, while the other proteins serve different functions in the body.
