Which signal word would you expect on a pesticide labeled as Category 3?

Explanation:
Signal words on pesticide labels convey how toxic a product is with respect to acute exposure, guiding how carefully you should handle it. Category 3 pesticides have lower acute toxicity than the higher-risk categories, so the label uses the milder word “Caution.” Danger warns of high toxicity and requires the strongest precautions; Warning signals moderate toxicity; None would imply no hazard signaling, which isn’t appropriate when there is any risk. So, the best fit is “Caution.”
