Answer

To answer the question "Stapes is attached to the", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Ear**:
- The human ear consists of three main parts: the outer ear, the middle ear, and the inner ear. The stapes is one of the three small bones located in the middle ear, along with the malleus and incus.

2. **Identify the Function of the Stapes**:
- The stapes, also known as the stirrup bone, is the smallest bone in the human body. Its primary function is to transmit sound vibrations from the incus (the middle bone) to the inner ear.

3. **Locate the Connection Points**:
- The stapes is connected to the oval window, which is a membrane-covered opening that leads from the middle ear to the inner ear. This connection is crucial for the process of hearing.

4. **Evaluate the Options**:
- **Tympanic Membrane**: This is the eardrum, which is connected to the malleus, not the stapes.
- **Oval Window**: This is the correct answer as the stapes is attached here.
- **Fenestra Rotunda**: This is another opening in the inner ear but is not where the stapes is attached.
- **Foza Ovalis**: This term is incorrect in the context of the ear; it refers to a structure in the heart.

5. **Conclusion**:
- Based on the above analysis, the stapes is attached to the oval window.

### Final Answer:
The stapes is attached to the **oval window**.
