Hint: The skin is the largest organ of the human body. It covers the entire body. It prevents heat, light, injury and infection. The skin also: Regulates body temperature, Store water and fat Is a sense organ Prevent moisture loss, prevent bacteria from entering, Act as a barrier between the organism and its environment, Exposure to the sun helps to make vitamin D.

Complete answer:
The epidermis is the outermost layer of skin, which provides a waterproof barrier and creates our skin tone effectively. And the epidermis contains tough connective tissue, hair follicles, and sweat glands. And the deeper subcutaneous tissue is made of fat and connective tissues.
The epidermis does not contain blood vessels, instead cells in the deepest layers are nourished by diffusion from blood capillaries that are present in the upper layers of the dermis. Diffusion provides nourishment and their waste removed from the cells of the dermis, as well as for the cells of the epidermis.
Epidermis is the top layer of skin. And dermis is the second layer of skin. The dermis is tough but the elastic support structure of nerves, blood vessels, lymphatics, and appendages. It is thicker (averages 1 to 4 mm) than the epidermis which is about as thin as a piece of paper. And the epidermis is the outermost layer of the three layers of skin. Its thickness is depending on where it is located on the body.
Thus the correct answer is option ‘C’.

Note: Epidermis is the outermost protective layer of skin. And it consists of dead cells called corneocytes. It is also responsible for our skin colour. Dermis is the below layer and epidermis and the middle layer. Which contains tough connective tissues, hair follicles and a sweat gland.
