Which materials should never be disposed of in regular trash?

The correct choice highlights the importance of safely managing hazardous or toxic materials. These materials can pose serious risks to human health and the environment if they are not disposed of correctly. They may include chemicals, batteries, certain types of electronics, and substances that are flammable, corrosive, or reactive. When these materials are placed in regular trash, they can contaminate soil and water supplies, harm wildlife, and create unsafe conditions for waste management workers.

Proper disposal methods for hazardous or toxic materials typically involve specific recycling programs or hazardous waste collection sites designed to handle these substances safely. This approach helps to mitigate risks associated with exposure and environmental pollution, ensuring that they are treated with the care and responsibility they require.
