Choose the correct set of disease transmitting arthropods

Options

A. Tsetse fly, house fly, rat flea, sand fly
B. Anopheles, louse, house fly, termite
C. Cockroach, louse, termite, housr fly
D. Rat flea, butterfly, house fly, tse-tse fly.

Answer

To solve the question regarding the correct set of disease-transmitting arthropods, we will analyze each option provided and identify which arthropods act as vectors for diseases.

### Step-by-Step Solution:

1. **Identify the Arthropods in Each Option**:
- Look at the list of arthropods provided in each option. Common vectors include flies, fleas, and other insects.

2. **Research Each Arthropod's Role as a Vector**:
- **C. C. Fly (Tsetse Fly)**: This is known to transmit *Trypanosoma gambiense*, which causes sleeping sickness.
- **Housefly**: This insect is a vector for various diseases, including typhoid fever and amoebic dysentery, primarily through contaminated food and water.
- **Rat Flea (Xenopsylla)**: This flea is a vector for the bubonic plague.
- **Sand Fly (Phlebotomus)**: This fly transmits *Leishmania donovani*, which causes Kala Azhar (Dum-Dum Fever).

3. **Evaluate Each Option**:
- **Option 1**: C. C. Fly, Housefly, Rat Flea, Sand Fly.
- All these arthropods are known vectors for diseases.
- **Option 2**: Anopheles (malaria), Louse (typhus fever), Housefly, Termite.
- Anopheles and Louse are vectors, but Termite is not a vector.
- **Option 3**: Cockroach, Housefly, Termite, Rat Flea.
- Cockroaches can contaminate food but are not considered primary disease vectors, and Termite is not a vector.
- **Option 4**: Butterfly, Housefly, Rat Flea, Sand Fly.
- Butterfly is primarily a pollinator and does not transmit diseases.

4. **Select the Correct Option**:
- After evaluating all options, **Option 1** is the only set where all arthropods listed are confirmed vectors for diseases.

### Final Answer:
The correct set of disease-transmitting arthropods is **Option 1: C. C. Fly, Housefly, Rat Flea, and Sand Fly.**
