Assertion : The areas fall between the boundaries of two plates are called seismic or fault zones.
Reason : Fault zones are earthquake free zones.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "The areas fall between the boundaries of two plates are called seismic or fault zones."
- This is true because seismic zones or fault zones are indeed the areas where tectonic plates meet, and these zones are characterized by geological activity, including earthquakes.

2. **Understanding the Reason**:
- The reason states that "Fault zones are earthquake free zones."
- This statement is false. Fault zones are actually areas where earthquakes are likely to occur due to the movement of tectonic plates. They are not free from earthquakes; rather, they are prone to them.

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

### Final Answer:
- The assertion is true, and the reason is false.
