Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Epidermis.
Therefore option C, Epidermis, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Epidermis The Epidermis is the outermost layer of the skin. Epidermis contains Keratinocytes (produce keratin for protection) and Melanocytes (produce melanin for skin color). Dermis — Dermis is the middle/second layer of skin beneath the epidermis; contains hair follicles, sweat glands, blood vessels, and nerve endings. Hypodermis — Hypodermis (Subcutaneous layer) is the deepest layer of skin; mainly consists of fat and connective tissue for insulation and energy storage. Subcutaneous layer — Same as Hypodermis, the deepest layer; not the outermost. 📝 Important Note: Skin has 3 layers: Epidermis (outermost), Dermis (middle), Hypodermis/Subcutaneous (innermost). Skin is the largest organ of the human body. Epidermis has 5 sub-layers (strata). Melanin in epidermis determines skin color and protects from UV rays.
