Which of the following are the layers of the skin?

The layers of the skin are composed of the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and serves as a protective barrier against environmental factors, providing waterproofing and skin tone due to its pigmentation. Below the epidermis lies the dermis, which contains connective tissue, blood vessels, nerves, and hair follicles, playing a crucial role in sensation, nourishment, and temperature regulation of the skin.

The hypodermis, also known as the subcutaneous layer, is the deepest layer that connects the skin to underlying tissues and organs. It consists mostly of adipose (fat) tissue, which provides insulation and cushioning for the body.

This option accurately represents the anatomical structure of the skin in a way that aligns with standard biological classification, whereas other choices either omit a layer or misconstrue the terminology used to describe the layers of the skin.
