D. If both Assertion and Renson are false.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Overpopulation causes a number of socio-economic problems."
- This means that when the population exceeds the available resources, it leads to issues such as food shortages, increased poverty, illiteracy, and higher crime rates.

2. **Understanding the Reason**:
- The reason states that "A number of bacterial and viral diseases have been controlled."
- This indicates that advancements in medicine, such as antibiotics and antiviral drugs, have helped in managing diseases that were once prevalent.

3. **Evaluating the Relationship**:
- While both statements are true, the reason does not explain the assertion. The control of diseases does not directly relate to the socio-economic problems caused by overpopulation.
- The assertion focuses on the consequences of overpopulation, while the reason discusses medical advancements, which are unrelated to the socio-economic issues caused by overpopulation.

4. **Choosing the Correct Option**:
- Based on the analysis, we find that:
- Both the assertion and reason are true.
- However, the reason is not a correct explanation of the assertion.
- Therefore, the correct answer is: **Both assertion and reason are true, but reason is not a correct explanation of assertion.**

### Final Answer:
The correct answer is the second option.
