Which practice helps maintain product quality by prioritizing older stock?

• A. First In, First Out
• B. Last In, Last Out
• C. First Out, First In
• D. First In, Last Out

Answer: (A)

Prioritizing older stock helps preserve quality by moving the oldest items out for sale or use first. This rotation keeps perishable or aging products from sitting on shelves too long, reducing spoilage and waste while maintaining freshness for customers. The approach that accomplishes this is First In, First Out: the oldest inventory is used before newer stock, so items are sold while still within their quality window. Using newer stock first would allow older items to deteriorate, and other ordering ideas don’t reliably ensure that oldest items are consumed first. So, to maintain product quality by prioritizing older stock, you employ First In, First Out.
