### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Kala Azar
- B) Sleeping sickness
- C) Typhoid
- D) Dysentery

2. **Analyze Kala Azar**:
- Kala Azar is also known as Leishmaniasis.
- It is caused by the protozoan parasite *Leishmania*.
- The transmitting agent (vector) for Kala Azar is the sandfly.
- Therefore, sandfly is indeed a transmitting agent of Kala Azar.

3. **Analyze Sleeping Sickness**:
- Sleeping sickness is caused by the protozoan parasite *Trypanosoma brucei*.
- The vector for this disease is the tsetse fly, not the sandfly.
- Hence, sandfly is not a transmitting agent of sleeping sickness.

4. **Analyze Typhoid**:
- Typhoid fever is caused by the bacterium *Salmonella typhi*.
- It is transmitted through contaminated food and water, not by a vector.
- Therefore, sandfly is not a transmitting agent of typhoid.

5. **Analyze Dysentery**:
- Dysentery can be caused by the bacterium *Shigella* or the protozoan *Entamoeba histolytica*.
- Similar to typhoid, it is spread through contaminated food and water.
- Thus, sandfly is not a transmitting agent of dysentery.

6. **Conclusion**:
- Based on the analysis, the only disease for which the sandfly is a transmitting agent is Kala Azar.
- Therefore, the correct answer is **A) Kala Azar**.
