Final answer:
The concept in question is derivative classification, which means that the new document should be classified at the same level as the highest classification of the information it contains, in this case, Confidential.
Step-by-step explanation:
The student is asking about the derivative classification concept as it pertains to a document that includes information regarding a unit's budget, which has been classified as Confidential in the Security Classification Guide (SCG).
When a new document incorporates information from various classified sources, the classification level of this new document is determined by the highest level of the classified information that is included. In this case, since the unit's budget is classified as Confidential and assuming that no other higher classification information is included or compiled in this document, the new document would typically inherit that Confidential classification level.
This document can be classified using the derivative classification concept of Compilation Classification. According to the Security Classification Guide (SCG), the budget is classified as Confidential, the Schedule of Distribution is also classified as Confidential, but when both the budget and Schedule of Distribution are compiled together, the document is classified as Secret.
In this case, the new document states the department's budget for the quarter is $64,000, which falls under the compiled information and therefore, is classified as Secret.
