Select the mismatch.

Options

A. AIDS - ELISA test (Diagnosis)
B. Filariasis - Wuchereria (Causative organism)
C. Malaria - Anopheles mosquito (Causative agent)
D. Ringworm - Dry, Scaly lesions on skin (Symptoms)

Answer

To solve the question "Select the mismatch," we will analyze each option provided to determine which one is incorrect.

### Step-by-Step Solution:

1. **Option 1: AIDS - ELISA Test Diagnosis**
- **Explanation**: AIDS (Acquired Immunodeficiency Syndrome) is diagnosed using the ELISA (Enzyme-Linked Immunosorbent Assay) test, which detects the presence of HIV (Human Immunodeficiency Virus) in the body. This option is correct.

2. **Option 2: Filariasis - Causative Organism**
- **Explanation**: Filariasis is caused by the parasitic worm Wuchereria bancrofti. This option correctly matches filariasis with its causative organism. Therefore, this option is also correct.

3. **Option 3: Malaria - Anopheles Mosquito Causative Agent**
- **Explanation**: Malaria is caused by the Plasmodium species, which are protozoan parasites. The Anopheles mosquito is not the causative agent; rather, it is the vector that transmits the Plasmodium from one host to another. This option is incorrect, making it a mismatch.

4. **Option 4: Ringworm - Dry Scaly Lesions on Skin**
- **Explanation**: Ringworm is a fungal infection that presents with symptoms such as dry, scaly lesions on the skin. This description is accurate, and thus this option is correct.

### Conclusion:
The mismatch in the options provided is **Option 3**: "Malaria - Anopheles mosquito causative agent," because the Anopheles mosquito is the vector, not the causative agent.

### Final Answer:
**Option 3 is the mismatch.**
