Which of the following statement is false?

Options

A. treatment of AIDS with anti-retroviral drugs is only partially effective.
B. Normal cells show a property of contact inhibition.
C. Treatment of AIDS can only prolong the life of the patient but cannot prevent death, which is inevitable.
D. T-Cytotoxic cell continue to produce HIV and in this way acts as HIV factory.

Answer

To determine which statement is false among the given options, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Analyze the first statement**:
- "Treatment of AIDS with antiretroviral drug is only partially effective."
- This statement is true. Antiretroviral drugs can manage HIV infection but do not cure AIDS. They help prolong the life of the patient but are not completely effective in eradicating the virus.

2. **Analyze the second statement**:
- "Normal cells show a property of contact inhibition."
- This statement is also true. Normal cells stop dividing when they come into contact with each other, which is known as contact inhibition. This property helps prevent uncontrolled cell growth.

3. **Analyze the third statement**:
- "Treatment of AIDS can only prolong the life of the patient but cannot prevent the death which is inevitable."
- This statement is true as well. While antiretroviral therapy can extend the life of an AIDS patient, it cannot prevent death from the disease.

4. **Analyze the fourth statement**:
- "Cytotoxic T-cells will continue to produce HIV and in the way act as an HIV factory."
- This statement is false. Cytotoxic T-cells (also known as cytotoxic T lymphocytes) do not produce HIV. Instead, it is primarily macrophages that act as factories for HIV replication. Cytotoxic T-cells are involved in killing infected cells but do not replicate the virus themselves.

### Conclusion:
The false statement among the options is the fourth one: "Cytotoxic T-cells will continue to produce HIV and in the way act as an HIV factory."
