• D. None of the above

Answer 1

The correct option is C Pathogens

• The outer layer of skin, the epidermis, provides waterproofing and serves as a barrier to infection.
• The middle layer of skin, the dermis, contains blood vessels, nerves, and glands that are important for our skin's function.
• The inner layer of the skin, the subcutis, contains fat that protects us from trauma. Hence, Epidermis serves as a barrier to Pathogens.

So, the correct answer is 'Pathogens'.
