B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertin is true but reason is false.
D. If both assertion and reason are false.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that antiretroviral drugs are very effective in the treatment against AIDS. We need to evaluate this statement based on the effectiveness of these drugs.

2. **Evaluating the Effectiveness of Antiretroviral Drugs**: Antiretroviral drugs are indeed used to manage HIV infections, which can lead to AIDS. However, while these drugs can help prolong the life of patients and improve their quality of life, they do not cure AIDS or completely prevent death from the disease. Therefore, the assertion is misleading as it implies a higher level of effectiveness than what is true.

3. **Understanding the Reason**: The reason provided states that the AIDS virus is a retrovirus with single-stranded DNA as genetic material. We need to verify the accuracy of this statement.

4. **Evaluating the Nature of the AIDS Virus**: The virus that causes AIDS is HIV (Human Immunodeficiency Virus), which is indeed a retrovirus. However, it contains single-stranded RNA, not DNA. Thus, the reason given is incorrect.

5. **Conclusion**: Since both the assertion and the reason are incorrect, we can conclude that the correct answer is that both the assertion and reason are false.

**Final Answer**: Both the assertion and reason are false.
