D. `KmnO_4`

Answer

To determine which of the following options are examples of herbicides, we first need to understand what herbicides are and their function.

### Step-by-Step Solution:

1. **Definition of Herbicides**:
- Herbicides are a type of pesticide specifically designed to kill or inhibit the growth of unwanted plants, commonly referred to as weeds. They are used in agriculture to protect crops from competition with these weeds.

2. **Function of Herbicides**:
- Herbicides work by targeting specific biological processes in plants. They can be selective (targeting certain types of plants while leaving others unharmed) or non-selective (killing all plant material they come in contact with).

3. **Identifying Examples**:
- To answer the question, we need to identify substances that are classified as herbicides. Common examples include:
- Glyphosate
- Atrazine
- 2,4-Dichlorophenoxyacetic acid (2,4-D)
- Paraquat

4. **Reviewing Options**:
- If provided with options, we would compare each option against our list of known herbicides. Any option that matches one of the herbicides listed above would be considered a correct example.

5. **Conclusion**:
- Based on the understanding of herbicides and their function, we can conclude which options are correct examples of herbicides.
