Answer

To determine which of the given options is anatomically correct in the human body, we need to analyze each option provided:

1. **Collarbones (Clavicles)**:
- In humans, there is **only one pair** of collarbones (clavicles). Therefore, this option is incorrect.

2. **Salivary Glands**:
- Humans have **three pairs** of salivary glands: the parotid glands, submandibular glands, and sublingual glands. This option is also incorrect.

3. **Cranial Nerves**:
- Humans have **twelve pairs** of cranial nerves. This option is incorrect as well.

4. **Floating Ribs**:
- Humans have **two pairs** of floating ribs (the 11th and 12th pairs). These ribs are not attached to the sternum and are known as floating ribs. This option is correct.

Based on the analysis, the anatomically correct statement is that there are **two pairs of floating ribs** in the human body.

### Final Answer:
The anatomically correct option is: **Floating ribs: 2 pairs.**
