Answer

To solve the question "If the thrombus floats in the blood, it is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- A **thrombus** is a blood clot that forms in a blood vessel and remains attached to its place of origin.
- An **embolus** is a mass (which can be a thrombus) that has detached and is now floating in the bloodstream.

2. **Analyze the Question**:
- The question specifically asks about a thrombus that is floating in the blood. This indicates that the thrombus is no longer attached to the vessel wall.

3. **Identify the Correct Option**:
- Given the options:
- A) Thrombus
- B) Embolus
- C) Aneurysm
- D) Hematoma
- Since a floating thrombus is referred to as an embolus, the correct answer is **Option B: Embolus**.

4. **Conclusion**:
- Therefore, if the thrombus floats in the blood, it is called an **embolus**.

### Final Answer:
**Option B: Embolus**
