The words _________ appear on the labels of pesticides that are highly toxic.

• A. Use with care
• B. Warning
• C. Danger-Poison
• D. Caution

Answer: (C)

Pesticide labels use signal words to show how dangerous a product is. When a product is highly toxic, the strongest warning is shown as “Danger-Poison.” This combination flags that even small exposures can cause serious harm or death, so you must take strict precautions—wear appropriate protective gear, avoid inhalation or contact, and keep others away during handling.

The other terms indicate lower levels of hazard. “Warning” is used for products that are harmful but not as dangerous as those labeled with Danger-Poison, and “Caution” is for the least hazardous products. “Use with care” isn’t an official hazard signal on labels, so it doesn’t communicate the same level of risk.
