The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Analogous organs are a result of divergent evolution." We need to analyze this statement. - **Explanation**: Analogous organs are those that perform similar functions but have different structural origins. They arise from convergent evolution, where different species evolve similar traits due to adapting to similar environments, not from a common ancestor. 2. **Understanding the Reason**: The reason provided is "Eye of Octopus and that of mammals depict divergent evolution." - **Explanation**: The eyes of octopuses and mammals are indeed similar in function (both serve the purpose of vision) but differ in structure and embryonic origin. This similarity in function despite different structures is an example of convergent evolution, not divergent evolution. 3. **Evaluating the Truth of the Statements**: - The assertion is **false** because analogous organs result from convergent evolution, not divergent evolution. - The reason is also **false** because the eye structures of octopuses and mammals do not depict divergent evolution; they are an example of convergent evolution. 4. **Conclusion**: Since both the assertion and the reason are incorrect, the correct answer is (D) both are wrong. ### Final Answer: (D) Both are wrong. ---
