A. Iris
B. Cornea
C. Sclerotic
D. Retina

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the location of the black pigment in the eye that reduces internal reflection.

2. **Identifying the Options**: The options given are:
- A) Iris
- B) Cornea
- C) Sclerotic
- D) Retina

3. **Analyzing Each Option**:
- **Iris**: This is the colored part of the eye that controls the size of the pupil, thus regulating the amount of light that enters the eye.
- **Cornea**: This is the transparent front part of the eye that covers the iris and pupil. It helps in focusing light but does not contain the black pigment.
- **Sclerotic**: This refers to the tough outer layer of the eye, which provides protection and structure. It does not contain the black pigment.
- **Retina**: This is the light-sensitive tissue located at the back of the eye. It contains photoreceptor cells and is responsible for converting light into neural signals. The black pigment in the retina helps to reduce internal reflection.

4. **Conclusion**: The correct answer is **D) Retina**. The black pigment located in the retina helps to minimize internal reflection and controls the impact of bright light entering the eye.
