Sarita stored some blue crystals in water. She obtained a clear, blue liquid. Which of the following is correct about the change that took place?

Options

A. The crystals melted and spread out in water to give a solution.
B. The crystals dissolved in water to give a solution.
C. The crystals were absorbed by water to give a suspension.
D. The crystals dissolved in water to give a suspension.

Answer

To solve the question about Sarita's experiment with blue crystals and water, we will analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Experiment**:
- Sarita stored blue crystals in water and observed that she obtained a clear blue liquid. This indicates a change has occurred in the physical state of the blue crystals.

**Hint**: Think about what happens when a solid is mixed with a liquid.

2. **Identifying the Type of Change**:
- The blue crystals did not remain as solid pieces; instead, they transformed into a liquid form that is uniformly blue. This suggests that the blue crystals have mixed with the water.

**Hint**: Consider whether the solid is still present or if it has changed into something else.

3. **Defining the Mixture**:
- The resulting clear blue liquid indicates that the blue crystals have dissolved in the water. A clear blue liquid means that the mixture is homogeneous, meaning it has a uniform composition throughout.

**Hint**: Recall the definitions of homogeneous and heterogeneous mixtures.

4. **Conclusion**:
- Since the blue crystals dissolved in water to form a clear blue liquid, the correct statement about the change that took place is that "the crystal dissolved in water to give a solution." This is a characteristic of a homogeneous mixture.

**Hint**: Look for the option that describes the process of dissolving rather than melting or forming a suspension.

### Final Answer:
The correct option is that "the crystal dissolved in water to give a solution."
