Answer

To determine which agricultural tool is used to remove weeds in a field, let's analyze the options provided:

1. **Harrow**: This tool is specifically designed for breaking up and aerating the soil, and it is effective in removing weeds. It has a shape that allows it to cut through the soil and uproot weeds as it is dragged across the field.

2. **Leveler**: This tool is used to level the field. It has a heavy metal block that helps in flattening the soil but does not serve the purpose of removing weeds.

3. **Plow**: The plow is primarily used for tilling the soil and preparing it for planting seeds. While it may disturb weeds, its main function is not to remove them.
