D. If both assertion and reason are false.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Fungicides act against fungal pathogens."
- This is true because fungicides are specifically designed to target and kill fungi that can cause diseases in plants.

2. **Understanding the Reason**:
- The reason provided is that "Fungicides are not harmful for human beings."
- This statement is misleading. While fungicides are used in agriculture, they can have harmful effects on humans, such as causing irritation to the skin and eyes.

3. **Evaluating the Truth of Each Statement**:
- The assertion is true: Fungicides do act against fungal pathogens.
- The reason is false: Fungicides can indeed be harmful to humans.

4. **Conclusion**:
- Since the assertion is true and the reason is false, the correct answer is that the assertion is true but the reason is false.

### Final Answer:
The correct option is: Assertion is true but reason is false.
