Answer

To solve the question "Choose the wrong statement regarding the human ear," we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Stapes is attached to tympanic membrane."
- The stapes is one of the three ossicles in the middle ear. However, it is not attached to the tympanic membrane. The malleus is the ossicle that is attached to the tympanic membrane. Therefore, this statement is **incorrect**.

- **Statement 2**: "Eustachian tube connects middle ear cavity with pharynx."
- The Eustachian tube does connect the middle ear to the pharynx, helping to equalize pressure. This statement is **correct**.

- **Statement 3**: "Middle ear contains three ossicles."
- The middle ear indeed contains three ossicles: malleus, incus, and stapes. This statement is **correct**.

- **Statement 4**: "Cochlea called scala media is filled with endolymph."
- The scala media is a part of the cochlea and is filled with endolymph. This statement is **correct**.

2. **Conclusion**:
- The only incorrect statement is the first one: "Stapes is attached to tympanic membrane." Hence, this is the wrong statement regarding the human ear.

### Final Answer:
The wrong statement regarding the human ear is: **"Stapes is attached to tympanic membrane."** (Statement 1)
