Explanation

Reserve samples serve a critical quality assurance function: they provide documented, retained portions of materials or finished products that can be tested at a future date if questions arise about product quality, stability, or safety - this is a core regulatory requirement in industries like pharmaceuticals, food manufacturing, and cosmetics (e.g., under FDA 21 CFR 211.170). Option A is wrong because display is not a scientific or regulatory purpose for retaining samples. Option C is wrong because reserve samples are not about maintaining excess inventory - they are typically minimal, precisely controlled quantities. Option D is wrong because training personnel is handled through separate reference standards and training materials, not regulatory reserve samples.

Memory tip: Think of reserve samples as your "legal insurance policy" - they exist to protect both the manufacturer and the consumer by allowing independent re-testing if a complaint, recall, or regulatory audit ever occurs.
