Which of the following is NOT listed as a type of herbicide?

Explanation:
Herbicides are organized by how they work or when they’re used. A contact herbicide kills plant tissue on contact, a pre-emergence herbicide is applied to the soil to prevent weed seedlings from emerging, and selective herbicides are designed to harm certain plants while sparing others, like crops. Roundup, however, is a brand name for glyphosate—a specific product, not a category of herbicide. Brand names describe a product, while the other terms describe the way the herbicide behaves or when it’s applied. So Roundup isn’t a type of herbicide, making it the correct answer.
