The primary barrier to protect the body against disease is:

1. **Short fingernails**: While keeping fingernails short can help reduce the accumulation of dirt and bacteria, it is not the primary barrier against disease.

2. **Unbroken skin**: The skin acts as a physical barrier that prevents pathogens from entering the body. When the skin is intact and unbroken, it effectively protects against infections.

3. **Protective gloves**: Wearing gloves can provide a barrier against contaminants, especially in healthcare settings or when handling hazardous materials. However, it is not the primary natural barrier of the body.

4. **Hand washing**: Regular hand washing is crucial for removing pathogens from the skin, but it is a preventive measure rather than a primary barrier.

Therefore, the correct answer is B: Unbroken skin.
