Long-term memory is meant to hold information for extended periods, far beyond what we use in the moment. It’s the store that lets you recall events, facts, and skills from a long time ago. In practice, memories stored in long-term memory can persist for years and often decades, supporting recall long after the information was learned. Among the given options, decades best captures this extended duration because minutes and hours align with short-term or working memory, while days still fall short of the enduring nature of long-term storage. Some memories can last even longer than decades, but for the purpose of this question, decades is the most accurate description of long-term memory’s typical span.
