In which of the following organisms Malpighian tubule is found?

Options

A. Honey bee
B. Frog
C. Ascaris lumbricoides
D. Rabbit

Answer

**Step-by-Step Solution:**

1. **Understanding Malpighian Tubules**: Malpighian tubules are excretory and osmoregulatory structures found in certain organisms. They play a crucial role in the excretion of waste and the regulation of osmotic balance.

2. **Identifying the Organisms**: The question provides four options: honey bee, frog, scarlet slumbricoid, and rabbit. We need to determine which of these organisms possesses Malpighian tubules.

3. **Classifying the Organisms**:
- **Honey Bee**: Belongs to the phylum Arthropoda, which is known to have Malpighian tubules.
- **Frog**: A member of the phylum Chordata, which does not have Malpighian tubules.
- **Scarlet Slumbricoid**: This is a type of annelid worm, which also does not have Malpighian tubules.
- **Rabbit**: Another member of the phylum Chordata, which lacks Malpighian tubules.

4. **Conclusion**: Among the given options, only the honey bee, which is an arthropod, has Malpighian tubules. These structures are typically found in the lining of the gut of arthropods and are responsible for waste excretion and osmoregulation.

5. **Final Answer**: The organism in which Malpighian tubules are found is the **honey bee**.
