Refer to the given passage. The mosquito P is a carrier of virus that spreads a disease Q. Another mosquito R is a carrier of protozoan S that spreads a disease called T.
Select the option which correctly identifies P, Q, R, S and T.

Options

A. P-Aedes, Q-Dengue, R-Anopheles, S-Plasmodium, T-Malaria
B. P-Tse-tse fly, Q-Dengue, R-Anopheles, S-Plasmodium, T-Malaria
C. P-Aedes, Q-Dengue, R-Tse-tse fly, S-Entamoeba, T-Amoebic dysentery
D. P-Tse-tse fly, Q-Dengue, R-Aedes,

Answer

To solve the question, we need to identify the correct entities for P, Q, R, S, and T based on the information provided about the mosquitoes and the diseases they spread.

### Step-by-Step Solution:

1. **Identify Mosquito P and Disease Q**:
- The passage states that mosquito P is a carrier of a virus that spreads disease Q.
- The most common mosquito known to spread a viral disease is the Aedes mosquito, which is known for spreading dengue fever.
- Therefore, we can conclude:
- **P = Aedes mosquito**
- **Q = Dengue fever**

2. **Identify Mosquito R and Protozoan S**:
- The passage mentions another mosquito R that carries a protozoan S, which spreads disease T.
- The female Anopheles mosquito is well-known for being a carrier of the protozoan Plasmodium, which causes malaria.
- Therefore, we can conclude:
- **R = Anopheles mosquito**
- **S = Plasmodium**
- **T = Malaria**

3. **Summarize the Findings**:
- Now we can summarize the findings:
- **P = Aedes mosquito**
- **Q = Dengue fever**
- **R = Anopheles mosquito**
- **S = Plasmodium**
- **T = Malaria**

### Final Answer:
- **P = Aedes mosquito**
- **Q = Dengue fever**
- **R = Anopheles mosquito**
- **S = Plasmodium**
- **T = Malaria**
