Answer: (B)

Verified step by step guidance

1. Step 1: Begin by identifying the primary function described in the question: covering the external surface of the body and protecting deeper tissues.
2. Step 2: Recall the major systems of the body and their functions. For example, the skeletal system provides structural support, the muscular system enables movement, the digestive system processes food, and the integumentary system includes the skin and its associated structures.
3. Step 3: Focus on the integumentary system, which is responsible for covering the external surface of the body (skin) and protecting deeper tissues from environmental damage, pathogens, and dehydration.
4. Step 4: Understand that the integumentary system includes components such as the epidermis, dermis, hair, nails, and glands, all of which contribute to its protective role.
5. Step 5: Conclude that the integumentary system is the correct answer based on its function of external coverage and protection, as described in the question.
