Pigment free plastids are

Options

A. Chloroplasts
B. Chromoplasts
C. Lysosomes
D. Leucoplasts

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about pigment-free plastids. Plastids are organelles found in plant cells and are involved in the synthesis and storage of food.

2. **Analyzing the Options**:
- **Chloroplast**: These are green plastids that contain chlorophyll, the pigment responsible for photosynthesis. Therefore, they are not pigment-free.
- **Chromoplast**: These plastids are responsible for the coloration of fruits and flowers and contain various pigments. Thus, they are also not pigment-free.
- **Lysosome**: This is not a plastid; it is a membrane-bound organelle involved in digestion and waste removal in cells. Hence, it is not a valid option.
- **Leukoplast**: These are colorless plastids that do not contain pigments. They are primarily involved in the storage of starch, fats, and proteins.

3. **Identifying the Correct Answer**: Since the question specifically asks for pigment-free plastids, the only option that fits this description is leukoplast.

4. **Conclusion**: The correct answer to the question "Pigment free plastids are" is **leukoplast**.
