B. Cornea and conjunctiva
C. Fibrous coat
D. Cornea

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the exposed transparent region of the eyeball.

2. **Understand the Options**: The options provided are:
- Uvea
- Cornea
- Conjunctiva
- Fibrous coat

3. **Define Each Option**:
- **Uvea**: This is the pigmented layer of the eye, which includes the iris, choroid, and ciliary body. It is located beneath the sclera and cornea.
- **Cornea**: This is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. It is responsible for focusing light and is the only part of the body that does not have blood supply; it absorbs oxygen directly from the air.
- **Conjunctiva**: This is a thin, transparent membrane that lines the eyelids and covers the front of the eye, protecting the cornea.
- **Fibrous coat**: This refers to the outer layer of the eye, which includes the sclera and cornea.

4. **Analyze the Correct Answer**: The exposed transparent region of the eyeball is primarily the cornea. The conjunctiva is also transparent but serves a protective role. Therefore, the best answer that represents the exposed transparent region is the **cornea**, and the conjunctiva also plays a role in protecting the eye.

5. **Conclusion**: The correct answer to the question is **cornea and conjunctiva**.
