Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion (A):**
- The assertion states that "Chromoplast is a colored plastid in corolla and ripened fruits."
- Chromoplasts are indeed a type of plastid that contain pigments responsible for the color of flowers (corolla) and fruits. Therefore, this statement is **True**.

2. **Understanding the Reason (R):**
- The reason provided states that "It has water soluble chlorophyll and carotenoid pigments."
- Chromoplasts primarily contain carotenoid pigments, which are responsible for the yellow, orange, and red colors in many fruits and flowers. However, chlorophyll is not found in chromoplasts; it is found in chloroplasts, which are responsible for photosynthesis. Therefore, this statement is **False**.

3. **Conclusion:**
- Since the assertion is true and the reason is false, we can conclude that the correct option is that the assertion is true, but the reason is false.

**Final Answer:**
- The correct answer is option 3: Assertion is true, but the reason is false.
