What does shelf life mean?

Answer and explanation

Correct answer: Time during which product remains usable under proper conditions

Shelf life is the established period during which a product is expected to remain within its approved quality specifications when stored under the stated conditions. Those specifications may include potency, purity, identity, safety, appearance, and physical or biological performance. The concept is based on stability data rather than on the size of the production vessel or the number of employees. Option A is correct because it describes continued usability under proper storage conditions. A fermenter’s length, the sound of a culture medium, and the number of workers do not define product shelf life. These are unrelated properties, so options B, C, and D are not valid.
