Answer

To solve the question regarding which disease is caused by arboviruses transmitted by arthropods, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Arboviruses**:
- Arboviruses are viruses that are transmitted by arthropods, primarily mosquitoes. They are responsible for several viral diseases.

2. **Analyzing the Options**:
- The options given are:
- a) Malaria
- b) Dengue
- c) Filariasis
- d) Amoebiasis

3. **Option a: Malaria**:
- Malaria is caused by the Plasmodium species, which is a protozoan, not a virus. It is transmitted by the female Anopheles mosquito. Therefore, this option is incorrect.

4. **Option b: Dengue**:
- Dengue is caused by the dengue virus, which is indeed an arbovirus. It is transmitted by the Aedes mosquito. This option is correct.

5. **Option c: Filariasis**:
- Filariasis is caused by parasitic roundworms, specifically filarial worms. It is transmitted by mosquitoes, but it is not caused by a virus. Thus, this option is incorrect.

6. **Option d: Amoebiasis**:
- Amoebiasis is caused by the protozoan Entamoeba histolytica. It is not transmitted by arthropods but rather through contaminated food and water. Therefore, this option is also incorrect.

7. **Conclusion**:
- After analyzing all the options, the only disease caused by an arbovirus transmitted by arthropods is **Dengue**.
