B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Humans exploited the variations that were present naturally in the wild populations of plants and animals."
- This is true because humans have historically used the genetic diversity found in wild species to enhance agricultural practices, improve livestock, and develop new varieties of crops.

2. **Understanding the Reason**:
- The reason given is "Variation is the degree by which progeny resembles from their parents."
- This statement is incorrect. Variation refers to the differences among individuals, meaning it describes how progeny differ from their parents, not how they resemble them.

3. **Evaluating the Relationship**:
- Since the assertion is true and the reason is false, we need to determine how they relate to each other.
- The reason does not correctly explain the assertion because the definition of variation provided is inaccurate.

4. **Conclusion**:
- Based on the evaluation, we conclude that the assertion is true, but the reason is false. Therefore, the correct answer is option C: "Assertion is true but reason is false."
