Toxicity: The waste contains toxic substances that pose a risk to human health or the environment when improperly managed.
Step 2: Analyze the options.
Ignitability: Correct, as it is one of the characteristics of hazardous waste.
Reactivity: Correct, as it is a key property defining hazardous waste.
Radioactivity: Incorrect, as radioactive waste is regulated separately under specific guidelines.
Toxicity: Correct, as toxic substances in waste contribute to its hazardous classification.
