Answer: (C)

The EPA signal word "Danger" indicates a high level of toxicity associated with a substance. This classification is used to alert individuals to the significant health risks that may arise from exposure to materials labeled with this signal word. The usage of "Danger" is meant to emphasize the potential for acute health effects, indicating that immediate action or precautions are necessary when handling or being in proximity to such materials.

In the context of hazardous materials, understanding these signal words and their associated meanings is crucial.
