Answer

To determine which organism resides in lymph nodes, we can follow these steps:

1. **Understand the Question**: The question asks for an organism that specifically resides in lymph nodes. This implies we are looking for a pathogen or parasite that infects or lives within these structures.

2. **Review the Options**: The options provided are:
- A. Tenia
- B. Wuchereria
- C. Plasmodium
- D. Diplococcus

3. **Analyze Each Option**:
- **Tenia**: This refers to tapeworms, which primarily reside in the intestines, not lymph nodes.
- **Wuchereria**: This is a genus of parasitic roundworms, specifically Wuchereria bancrofti, which is known to cause lymphatic filariasis (elephantiasis) and resides in the lymphatic system, including lymph nodes.
- **Plasmodium**: This is the parasite that causes malaria, and it primarily resides in the liver and red blood cells, not lymph nodes.
- **Diplococcus**: This refers to a type of bacteria, which does not specifically reside in lymph nodes.

4. **Identify the Correct Answer**: Based on the analysis, Wuchereria (specifically Wuchereria bancrofti) is the organism that resides in lymph nodes and causes lymphatic filariasis.

5. **Conclude**: Therefore, the correct answer to the question is option B: Wuchereria.
