Assertion:Analogous organs serve the same function and look alike, but have different structure and embroyonic origin.
Reason:Analogous organs have no specific significance

Options

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

Answer

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

### Step 1: Understand the Assertion
The assertion states: "Analogous organs serve the same function and look alike, but have different structure and embryonic origin."

- **Explanation**: Analogous organs are those that perform similar functions but have different structural characteristics and embryonic origins. For example, the wings of birds and insects serve the same purpose (flight) but are structurally different and develop from different embryonic tissues.

### Step 2: Understand the Reason
The reason states: "Analogous organs have no specific significance."

- **Explanation**: This statement is incorrect. Analogous organs are significant in the study of evolution because they demonstrate convergent evolution, where different species evolve similar traits independently due to similar environmental pressures, despite having different ancestral origins.

### Step 3: Analyze the Truth of Each Statement
- The assertion is **true** because it accurately describes the nature of analogous organs.
- The reason is **false** because analogous organs do have significance, particularly in understanding evolutionary processes.

### Step 4: Conclusion
Based on the analysis:
- The assertion is true.
- The reason is false.

Thus, the correct option is that the assertion is true and the reason is false.

### Final Answer
The correct answer is: Assertion is true, Reason is false.
