What is the definition of 'perishable'?

The term 'perishable' specifically refers to items, particularly food, that have a limited shelf life and are likely to spoil or decay over time. This means that these items can become inedible or unusable if not consumed or preserved within a certain timeframe. The focus on the tendency to spoil makes this definition clear and direct, as it is often associated with organic materials such as fruits, vegetables, dairy products, and meats, which require careful handling and storage to maintain their quality and safety for consumption.

In contrast, the other options do not capture the essence of what 'perishable' signifies. Describing something as unchanging or long-lasting would imply durability and stability, while 'fresh' relates to the state of being recently produced or obtained rather than the inherent properties leading to spoilage. Thus, the definition of 'perishable' as likely to spoil or decay is the most accurate representation of the term.
