What does "contained in" mean in the context of derivative classification?

The phrase "contained in" in the context of derivative classification specifically refers to instances where classified information is directly extracted from its source in a verbatim manner. This is a crucial aspect of derivative classification because it emphasizes the importance of preserving the classification status of information that has been derived from already classified materials. When information is extracted word-for-word, it retains its original classification, and the individual handling this information must ensure it is appropriately marked and protected under the same classification standards.

This principle ensures that the integrity of the classified information is maintained and that any documents or materials derived from that information continue to uphold its confidentiality, integrity, and availability as designated by the original classification authority. In contrast to other options, which relate to different aspects of how information can be communicated or referenced, this concept specifically underscores the direct relationship between the extracted information and its source classification status.
