Which of the following is not a skin layer?

Explanation:
The skin is organized into three main layers: the epidermis on the outside, the dermis beneath it, and the hypodermis (subcutaneous tissue) deepest and mainly made of fat. Hair is anchored in the skin by hair follicles, which are specialized structures formed by downward invaginations of the epidermis into the dermis (and sometimes extending toward the hypodermis). Because a hair follicle is a structure within these layers rather than a distinct layer itself, it’s not considered a skin layer. That’s why the hair follicle is the correct answer.
