Answer

To answer the question "Tongue bone is," we will analyze the options provided and determine which one correctly identifies the tongue bone.

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the name of the bone that is referred to as the "tongue bone."

2. **Evaluate the Options**:
- **Option A: Mandible**: The mandible is known as the lower jaw bone. It is the longest bone in the facial skeleton but is not related to the tongue. Therefore, this option is incorrect.

- **Option B: Hyoid**: The hyoid bone is located in the neck, between the chin and the thyroid cartilage. It has a horseshoe shape and is often referred to as the "tongue bone" because it supports the tongue and its muscles. This option is correct.

- **Option C: Flat Bone**: This option is too general and does not specify a particular bone. While flat bones include structures like the skull and cranium, it does not pertain to the tongue bone. Thus, this option is incorrect.

- **Option D: Coccyx**: The coccyx, or tailbone, is a small triangular bone at the base of the spinal column. It is not associated with the tongue. Therefore, this option is also incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer to the question "Tongue bone is" is **B: Hyoid**.

### Final Answer:
The tongue bone is the **hyoid**.
