The term "retention" fundamentally relates to the concept of holding onto or maintaining possession of something over time. This can refer to various contexts, such as retaining information, keeping resources, or maintaining certain practices or technologies. The focus is on the idea of keeping or having something continue to be part of a system or individual possession.

In this context, the continued possession of something clearly captures the essence of retention. It underscores the idea of maintaining or persevering with something rather than eliminating or replacing it, which fits perfectly with the broader definition. Retention involves not just the act of keeping but also implies a sense of stability and continuity regarding what is held.

The other choices describe actions or concepts that do not encompass the idea of keeping or maintaining. For instance, discarding old technology implies removal rather than retention, while introducing new ideas suggests a change or transition rather than keeping what already exists. The temporary use of resources indicates a fleeting or non-permanent state, contrasting sharply with the notion of retaining something over a longer period.
