What is the correct order of priority for mandatory sources of supply?

The correct order of priority for mandatory sources of supply is based on established regulations that dictate the sequence in which different sources should be utilized when obtaining supplies or services. In this case, option B specifies the correct hierarchy: beginning with activity inventories allows organizations to first look within their own inventories for available supplies, which promotes efficiency and minimizes waste. Following this, UNICOR (Federal Prison Industries) is the next priority, as it serves as a source of goods produced by inmates, supporting rehabilitation while fulfilling government purchasing needs. NIB/NISH (National Industries for the Blind/National Institute for Severely Handicapped) come next, as they focus on providing products and services primarily sourced from individuals with disabilities, further reinforcing a commitment to supporting these communities. Finally, wholesale supply sources are considered last, as they are typically broader and may not offer the same specialized products that the previous options provide.

Each level focuses on maximizing the use of available resources while adhering to regulatory obligations that prioritize specific agencies and groups. This approach fosters sustainability and supports various national policies, such as those aimed at inclusivity and economic support for particular populations.
