Where should bait money orders be kept?

The correct response identifies the important practice surrounding the handling of bait money orders. Keeping bait money orders under the largest denomination is a procedural safeguard that ensures they are visibly distinct and easily accessible for use in controlled situations, such as setting up sting operations to catch criminals engaged in fraud or theft.

This method allows postal employees to quickly identify the bait money orders without confusion, as they are separated from standard cash transactions, creating a clear distinction in the handling of these funds.

The other choices suggest different handling practices that may not align with established protocols for bait money orders. For example, putting them in a locked drawer may not allow for the quick access required in active operations, while keeping them with personal cash can lead to potential mix-ups. Maintaining them in a separate account could complicate immediate access when needed for trap situations, undermining their purpose.
