B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

To solve the given question, we need to analyze both the assertion and the reason provided, and determine their truthfulness and relationship.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Most dangerous sexually transmitted disease is AIDS."
- AIDS (Acquired Immunodeficiency Syndrome) is indeed considered one of the most dangerous sexually transmitted diseases because it is caused by the Human Immunodeficiency Virus (HIV), which severely weakens the immune system.

**Hint**: Consider the impact of AIDS on the immune system and its transmission method.

2. **Understanding the Reason**:
- The reason states that "There is NO complete cure of AIDS."
- This statement is true. Currently, there is no complete cure for AIDS, although antiretroviral therapy (ART) can manage the disease and prolong the life of those infected.

**Hint**: Reflect on the current medical advancements regarding HIV/AIDS treatment and the concept of management versus cure.

3. **Evaluating the Relationship**:
- Now we need to determine if the reason provided is a correct explanation of the assertion.
- While both statements are true, the reason does not explain why AIDS is the most dangerous sexually transmitted disease. The assertion focuses on the danger of the disease, while the reason discusses the lack of a cure.

**Hint**: Think about whether the absence of a cure directly correlates to the danger level of the disease.

4. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not provide a correct explanation for the assertion, the appropriate answer is that both assertion and reason are true, but the reason is not a correct explanation of the assertion.

**Final Answer**: The correct option is that both assertion and reason are true, but the reason is not a correct explanation of the assertion.
