Answer: (B)

The primary function of the skin is to serve as a protective barrier. The skin plays a critical role in safeguarding the body from various external threats, including pathogens, chemicals, and physical injuries. It acts as the first line of defense against infection and protects underlying tissues from damage. Additionally, the skin helps to regulate body temperature and prevent excessive water loss, contributing to homeostasis. The protective barrier function is essential for overall health and well-being, as the skin not only shields from environmental factors but also contributes to the immune response, helping to identify and combat harmful organisms. This role is vital for maintaining the integrity of the body and ensuring proper functioning of other systems.
