Assertion :- Analogous structures are a result of convergent evolution.
Reason :- Different strutures evolving for the same function and hence having similarity.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is a 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

To solve the assertion-reason question, let's break it down step by step:

### Step 1: Understand the Assertion
The assertion states that "Analogous structures are a result of convergent evolution."
- **Explanation**: Analogous structures are features in different species that serve the same function but have different evolutionary origins. This is a key characteristic of convergent evolution, where unrelated species evolve similar traits due to similar environmental pressures.

### Step 2: Understand the Reason
The reason states that "Different structures evolving for the same function and hence having similarity."
- **Explanation**: This means that even though the anatomical structures are different, they have evolved to perform the same function. This is precisely what happens in convergent evolution, where different species develop similar adaptations in response to similar challenges.

### Step 3: Analyze the Relationship
Now, we need to analyze whether the reason correctly explains the assertion.
- The assertion is true because analogous structures do arise from convergent evolution.
- The reason is also true because it accurately describes how different structures can evolve to perform the same function, leading to the similarity observed in analogous structures.

### Step 4: Conclusion
Since both the assertion and the reason are correct, and the reason provides a correct explanation of the assertion, we conclude that:
- **Both assertion and reason are correct, and the reason is the correct explanation of the assertion.**

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