Which describes a non-systemic herbicide?

Non-systemic (contact) herbicides act locally and stay where they are applied; they do not move through the plant’s tissues. This means they affect only the parts of the plant that are directly contacted by the spray and don’t get transported to leaves, stems, or roots that weren’t treated. That’s why the best description is that the herbicide remains on the treated surface and does not move within the plant. In contrast, systemic herbicides are absorbed and moved within the plant (through xylem/phloem) to affect distant tissues, which is not characteristic of non-systemic products.
