Assertion (A) Analogous organs show common ancestry.
Reason (R) Analogous organs show evolution.

Options

A. Both Assertion and Reason are true and Reason is the correct explanation of the Assertion
B. Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion
C. Assertion is true, but Reason is false
D. Both Assertion and Reason are false

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion (A)
The assertion states: "Analogous organs show common ancestry."
- **Explanation**: Analogous organs are those that perform similar functions but have different structural features and developmental origins. For example, the wings of birds and insects serve the same purpose (flight) but are anatomically different. This indicates that they do not share a common ancestry. Therefore, the assertion is **false**.

### Step 2: Analyze the Reason (R)
The reason states: "Analogous organs show evolution."
- **Explanation**: While analogous organs do reflect evolutionary adaptations to similar environmental challenges (convergent evolution), they do not demonstrate a shared evolutionary lineage. Instead, they show how different species can evolve similar traits independently. Thus, this statement is also **false**.

### Step 3: Conclusion
Since both the assertion and the reason are false, we conclude that:
- **Both Assertion (A) and Reason (R) are false.**

### Final Answer
Both the assertion and reason are false.
