Assertion : Antiretroviral drugs are very effective in treatment against AIDS.
Reason : AIDS virus is a retrovirus with ssDNA as genetic material.

Options

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

Explanation

To solve the question, we need to analyze the given assertion and reason step by step.

### Step 1: Analyze the Assertion
The assertion states: "Antiretroviral drugs are very effective in treatment against AIDS."
- **Evaluation**: This statement is misleading. While antiretroviral drugs are effective in managing HIV (the virus that causes AIDS), they do not cure AIDS. Instead, they help control the virus and prevent the progression of the disease. Therefore, the assertion is **false**.

### Step 2: Analyze the Reason
The reason states: "AIDS virus is a retrovirus with ssDNA as genetic material."
- **Evaluation**: This statement contains a mix of truth and falsehood. It is true that the AIDS virus (HIV) is a retrovirus, but it is incorrect to say that it has single-stranded DNA (ssDNA) as its genetic material. HIV has single-stranded RNA (ssRNA) as its genetic material. Therefore, this statement is also **false**.

### Step 3: Determine the Relationship Between Assertion and Reason
Now that we have established that both the assertion and the reason are false, we can conclude their relationship:
- Since both the assertion and the reason are false, the correct answer to the question is **Option D**: Both assertion and reason are false.

### Final Answer
The answer to the question is **Option D**: Both assertion and reason are false.
