Information taken directly from an existing classified source and stated verbatim in a new document is an example of?

The correct choice is extracting, as this term specifically refers to taking information directly from an existing classified source and reproducing it in a new document. In the context of derivative classification, extracting implies that the verbatim information has been pulled from a classified source for the purpose of creating a new document, while retaining the original classification level of that information.

When extracting information, it is vital to ensure that any necessary handling rules and classification guidance are followed, to maintain the integrity and protection of the original information. This process involves a careful consideration of the content being used and ensures that the new document accurately reflects the classification requirements of the original source.

Alternative terms like copying and transcribing might suggest a similar action of reproducing information, but they do not encompass the specific legal and procedural implications associated with derivative classification. Reiterating generally implies the act of stating something again but does not capture the precise process of deriving information from existing classified materials. Thus, extracting is the most appropriate term for the scenario described.
