Coloured plastids containing fat soluble pigments like carotene and xanthophyll are :

Options

A. chloroplast
B. chromoplast
C. leucoplast
D. bioplast

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about colored plastids that contain fat-soluble pigments such as carotene and xanthophyll. We need to identify which type of plastid fits this description.

2. **Identifying Types of Plastids**: There are three main types of plastids:
- **Chloroplasts**: These plastids contain chlorophyll, the green pigment involved in photosynthesis.
- **Leucoplasts**: These are colorless plastids primarily involved in the storage of starch, oils, and proteins.
- **Chromoplasts**: These plastids contain pigments such as carotene (orange) and xanthophyll (yellow), which give color to fruits, flowers, and leaves.

3. **Analyzing the Options**:
- **Chloroplasts**: As mentioned, these contain chlorophyll and are not the correct answer since they do not contain carotene or xanthophyll.
- **Leucoplasts**: These are colorless and do not contain any pigments, so they are also not the correct answer.
- **Chromoplasts**: These plastids contain the fat-soluble pigments carotene and xanthophyll, making them the correct answer.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **Chromoplasts**.

**Final Answer**: Chromoplasts are the colored plastids containing fat-soluble pigments like carotene and xanthophyll.
