Which of the following pairs is correct?

Options

A. Wing of bats and insect wing are analogous
B. Ear of frog and ear of rabbit
C. Insect wing and bird wing are homologous
D. Wing of bat and flipper of seal

Answer

To determine which of the pairs listed in the question is correct, we need to analyze each option based on the concepts of analogous and homologous organs.

### Step-by-Step Solution:

1. **Understand Analogous Organs**:
- Analogous organs are those that have similar functions but different structures and evolutionary origins. They arise from convergent evolution.
- Example: The wings of bats and insects serve the same function (flying) but have different structures and evolutionary backgrounds.

2. **Understand Homologous Organs**:
- Homologous organs are those that have similar structures but may serve different functions. They arise from divergent evolution.
- Example: The forelimbs of mammals (like humans and whales) have similar bone structures but serve different functions (grasping vs. swimming).

3. **Evaluate Each Option**:
- **Option 1**: Wings of bats and insects are analogous.
- This is correct because both serve the function of flight but have different structures.
- **Option 2**: Ear of frog and ear of rabbit.
- This is incorrect as they are not homologous; their structures and functions differ significantly.
- **Option 3**: Insect wing and bird wing are homologous.
- This is incorrect as they are analogous; both serve the function of flight but have different structures.
- **Option 4**: Wings of bat and flippers of seal.
- This is incorrect as they serve different functions (flying vs. swimming) and are not homologous.

4. **Conclusion**:
- The only correct pair is **Option 1**: Wings of bats and insects are analogous.

### Final Answer:
The correct pair is: **Wings of bats and insects are analogous.**
