4. None

The correct answer is: Danger

The signal word that indicates a pesticide is highly toxic is "Danger." This classification is used to alert users to the potential hazards associated with the product. When "Danger" appears on a pesticide label, it signifies that the pesticide poses a significant risk of causing severe injury or illness through exposure even in small amounts. This word is part of a labeling system intended to communicate the level of toxicity and the urgency needed when handling the product. The signal words "Caution" and "Warning" indicate lower levels of toxicity. "Caution" is used for products that are considered less hazardous, while "Warning" signifies a moderate level of toxicity. In summary, "Danger" serves as a clear and immediate indicator of high toxicity, providing essential information for safe handling and application of pesticides.
