The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "Wings of butterfly and wings of bat are analogous organs." - To determine if this is true, we need to recall the definition of analogous organs. Analogous organs are those that perform similar functions but have different origins and structures. 2. **Understanding the Reason (R)**: - The reason states that "Analogous organs have different origin and structural plan but same function." - This definition aligns with our understanding of analogous organs, confirming that they do indeed have different origins and structures while serving a similar function. 3. **Analyzing the Wings of Butterfly and Bat**: - The wings of a bat are structurally similar to a human hand (they have bones and digits), while the wings of a butterfly are made of a different structure (membranous and covered with scales). - Both wings serve the function of flight, which supports the assertion that they are analogous organs. 4. **Evaluating the Relationship Between A and R**: - Since both the assertion (A) is true (they are indeed analogous organs) and the reason (R) is also true (the definition of analogous organs is accurate), we need to check if R correctly explains A. - The reason does explain why A is true, as it clarifies the nature of analogous organs. 5. **Conclusion**: - Since both A and R are true and R is the correct explanation of A, the correct option is: **a) Both A and R are true and R is the correct explanation of A.**
