Answer

To solve the question regarding the assertion and reason about HIV and AIDS, we can follow these steps:

### Step 1: Analyze the Assertion
The assertion states that "HIV is the most dangerous virus and disease AIDS is more focused nowadays."
- **Explanation**: HIV (Human Immunodeficiency Virus) is indeed considered one of the most dangerous viruses because it leads to AIDS (Acquired Immunodeficiency Syndrome), a condition that severely weakens the immune system. The focus on AIDS has increased due to its significant impact on global health.

### Step 2: Analyze the Reason
The reason provided is "It kills millions of people and drugs against it are not completely reliable."
- **Explanation**: This statement is also true. AIDS has caused millions of deaths worldwide, and while antiretroviral therapy can manage HIV infection, it is not a cure, and the effectiveness of these drugs can vary among individuals.

### Step 3: Determine the Relationship Between Assertion and Reason
Now we need to evaluate if the reason provided is a correct explanation of the assertion.
- **Explanation**: While both statements are true, the reason does not directly explain why HIV is considered the most dangerous virus. The assertion focuses on the danger of HIV as a virus, while the reason discusses the consequences of AIDS and the reliability of treatment.

### Step 4: Choose the Correct Option
Based on the analysis:
- Both the assertion and the reason are true.
- The reason does not provide a correct explanation for the assertion.

Thus, the correct answer to the question is:
**Option B**: Both assertion and reason are true, but reason is not a correct explanation of the assertion.
