Select the incorrect match.

Options

A. The solid that settles down when a heterogeneous solid-liquid mixture is allowed to stand - Filtrate
B. A solution in which no more solute can be dissolved - Saturated solution
C. Conversion of vapours to solid directly - Deposition
D. None of these

Explanation

To solve the question "Select the incorrect match," we need to analyze the given options and identify which one does not correspond correctly to its definition or description.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- We need to understand the terms mentioned in the options. For example, "sediment," "saturated solution," "deposition," and "dissublimation" are key terms that we need to clarify.

2. **Analyzing the First Option**:
- The first option refers to the solid that settles down when a heterogeneous solid-liquid mixture is allowed to stand. This solid is called "sediment." The transcript indicates that the term "filter rate" is incorrectly matched with this description.
- **Conclusion**: This option is incorrect because "filter rate" does not describe the solid that settles down.

3. **Analyzing the Second Option**:
- The second option discusses a "saturated solution," which is defined as a solution in which no more solute can be dissolved. This description is accurate.
- **Conclusion**: This option is correct.

4. **Analyzing the Third Option**:
- The third option refers to the process where vapor directly turns into solid, known as "deposition" or "dissublimation." The transcript confirms that this is also a correct match.
- **Conclusion**: This option is correct.

5. **Final Decision**:
- The only incorrect match identified is the first option, where "filter rate" is incorrectly associated with the solid that settles down in a heterogeneous mixture.

### Final Answer:
The incorrect match is the first option: "Filter rate" is not the correct term for the solid that settles down in a heterogeneous solid-liquid mixture.
