D. d) external ear with internal ear

Answer

To solve the question "Eustachian tube connects", we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Structure of the Ear**:
- The ear is divided into three main parts: the external ear, middle ear, and internal ear.
- The external ear is the outermost part, which includes the pinna and the ear canal.
- The middle ear is the space behind the eardrum that contains the ossicles (tiny bones).
- The internal ear (or inner ear) includes structures responsible for hearing and balance, such as the cochlea and vestibular system.

2. **Identifying the Eustachian Tube**:
- The Eustachian tube is a tube-like structure that connects the middle ear to another part of the body.
- Its primary function is to equalize air pressure in the middle ear and drain any mucus that may accumulate.

3. **Analyzing the Options**:
- **Option A**: Pharynx with middle ear.
- **Option B**: Middle ear with internal ear.
- **Option C**: Middle ear with external ear.
- **Option D**: External ear with internal ear.

4. **Determining the Correct Connection**:
- The Eustachian tube connects the middle ear to the nasopharynx (which is part of the pharynx).
- This connection allows for pressure equalization and drainage of mucus from the middle ear to the throat.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: Pharynx with middle ear**.

### Final Answer:
The Eustachian tube connects the pharynx with the middle ear.
