B. If both Assertion and Reason are true and the Reason is not the corret explanation of the Assertion .
C. If Assertion is ture the Reason is false .
D. If both Assertion and Reason are false .

Answer

To solve the question regarding the assertion and reason provided, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Minerals have a sedimentary cycle." This means that minerals undergo a cycle that involves their movement and transformation through various geological processes.

2. **Understanding the Reason**: The reason given is that "Their reservoir is in the earth's sediment." This indicates that the primary source or storage of these minerals is found within the sediments of the Earth.

3. **Evaluating the Assertion**:
- The statement about minerals having a sedimentary cycle is true. Minerals are indeed cycled through processes such as weathering, erosion, and deposition, which are characteristic of sedimentary cycles.

4. **Evaluating the Reason**:
- The reason is also true. Many minerals are found in sedimentary deposits, which serve as reservoirs for these minerals.

5. **Determining the Relationship**:
- Since both the assertion and the reason are true, we need to check if the reason correctly explains the assertion. The reason does explain why minerals have a sedimentary cycle, as it highlights that their reservoir is in the Earth’s sediments, which is part of the cycling process.

6. **Conclusion**:
- Therefore, both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
The correct option is: **Both assertion and reason are true, and reason is the correct explanation of the assertion.**
