Explanation:

The hair has different parts. The cuticle is the outermost layer that protects the hair. The shaft is the visible part of the hair above the skin. The root is inside the skin. The hair bulb is at the base of the hair root. The medulla is the innermost part of the hair (in some hairs). Since the question asks for the outer surface, the cuticle is the correct answer.
