A. Items that people discard such as yard trimmings, plastics, and glass.

Explanation:

Garbage can be defined as the unwanted waste discarded by humans, usually due to lack of utility or use. Human kind has been creating waste since history. It can be in the form of solid, liquid or gas. Wood pieces, glass, cardboard boxes, fruit coverings or peel are examples of garbage materials.

Garbage can be biodegradable and non-biodegradable waste. Biodegradable waste is one that can be decomposed by the natural activities of microbes whereas the non-biodegradable wastes are those which cannot be decomposed by the action of microbes.

The garbage waste materials can be toxic and hazardous or non-toxic or non-harmful. For example, the garbage discharged by the nuclear power plant can be hazardous as may contain harmful radiation. But garbage produce by paper industry will be non-harmful as the paper pulp will be decomposed by the microbes.
