Homologous organs are

Options

A. Wings of pigeon and Butterfly
B. Wings of Pigeon and Housefly
C. Wings of Pigeon and arms of Humans
D. Wings of Bat, Housefly and Butterfly

Answer

**Step-by-Step Solution:**

1. **Understanding Homologous Organs:**
- Homologous organs are defined as organs that have a similar origin or structure but may serve different functions in different organisms. This similarity in origin indicates a common ancestry.

2. **Analyzing the Options:**
- We need to evaluate the given options to identify which pair of organs are homologous.

3. **Option 1: Wings of Pheasant and Butterfly**
- Both the wings of a pheasant (bird) and a butterfly serve the function of flying. However, they do not share a common structural origin. Therefore, this option is incorrect.

4. **Option 2: Wings of Pigeon and Housefly**
- Similar to the first option, both the wings of a pigeon (bird) and a housefly (insect) are used for flying. They do not share a common structural origin either. Thus, this option is also incorrect.

5. **Option 3: Wings of Pigeon and Arms of Human**
- The wings of a pigeon and the arms of a human have a similar underlying skeletal structure (both are derived from the forelimbs of a common ancestor), but they serve different functions. Pigeons use their wings for flying, while humans use their arms for manipulation and various tasks. This option is correct.

6. **Option 4: Wings of Birds, Housefly, and Butterfly**
- This option includes wings from different classes of animals (birds and insects) that serve the same function of flying but do not share a common origin. Therefore, this option is incorrect.

7. **Conclusion:**
- After evaluating all the options, the correct answer is **Option 3: Wings of Pigeon and Arms of Human** as they are homologous organs.
