D. Triceps

Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about the types of muscles present in the tongue.

2. **Understand the Structure of the Tongue**: The tongue is an accessory digestive organ that is primarily composed of skeletal muscle tissue.

3. **Types of Muscles in the Tongue**:
- **Extrinsic Muscles**: These muscles are located outside the tongue and are responsible for moving the tongue side to side and in and out. They help in the manipulation of food and are important for swallowing and speech.
- **Intrinsic Muscles**: These muscles are located within the tongue itself and allow it to change shape and size. This capability is crucial for various functions, including speech and swallowing.

4. **Classification of Muscles**: Both extrinsic and intrinsic muscles of the tongue are classified as voluntary muscles because they are skeletal muscles. This means that their movements can be consciously controlled.

5. **Evaluate the Options**:
- **Involuntary**: Incorrect, as the tongue muscles are skeletal and voluntary.
- **Voluntary**: Correct, as both extrinsic and intrinsic muscles are voluntary.
- **Biceps**: Incorrect, as biceps are muscles of the upper arm, not the tongue.
- **Triceps**: Incorrect, as triceps are also muscles of the upper arm, not related to the tongue.

6. **Conclusion**: The correct answer is that the muscles of the tongue are voluntary.
