Symptoms of Chickenpox:
Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus. It mainly affects children but can also occur in adults who have not been immunized or previously infected with the virus. The symptoms of chickenpox include:

1. Fever and itchy rash:
- One of the initial symptoms of chickenpox is a fever, which may range from mild to high-grade.
- Along with the fever, the affected person develops a characteristic itchy rash all over the body.
- The rash initially appears as red spots or small bumps, which then develop into fluid-filled blisters.

2. Pimples, blisters, and scabs:
- As the rash progresses, the red spots or bumps turn into small fluid-filled blisters.
- These blisters can be itchy and may appear in different stages of development on different parts of the body.
- The blisters eventually burst and form scabs, which can be painful and take some time to heal.

3. Scabs drop after about two weeks:
- After the formation of scabs, they gradually dry up and fall off the skin.
- This process usually takes about two weeks from the onset of the rash.
- Once all the scabs have fallen off, the person is considered no longer contagious.

Identifying the disease:
Based on the given symptoms, the disease is most likely to be chickenpox (option C). This is because chickenpox is characterized by fever, itchy rash, and the presence of pimples, blisters, and scabs. The scabs dropping off after about two weeks is also consistent with the natural course of chickenpox.

Tuberculosis (option A) is a bacterial infection that primarily affects the lungs and does not typically present with fever and itchy rash. Typhoid (option B) is a bacterial infection that causes high fever, abdominal pain, and diarrhea but does not involve a rash. Cholera (option D) is a bacterial infection that causes severe diarrhea and dehydration and does not cause fever or rash.

In conclusion, based on the symptoms described, the disease is most likely to be chickenpox. It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
