The correct answer is Classification by Compilation. This concept applies specifically when unclassified information is combined to create a new document or material that contains classified information. In this context, the new material's classification arises not from the individual unclassified pieces of information but from the way they are compiled together, ensuring that the resulting structure grants it classification status due to the aggregating effect.

When different pieces of unclassified data come together in a manner that reveals sensitive or classified information, the classification is warranted. This principle emphasizes the importance of considering the overall impact of combined unclassified information rather than just evaluating the components in isolation. Understanding this concept is critical for those dealing with sensitive information to ensure compliance with classification guidelines and to mitigate security risks.

In contrast, the other concepts mentioned, such as revealed by and aggregate classification, do not directly address the process of combining unclassified material to derive a classified status, while composite classification more specifically refers to the classification of material that incorporates classified elements together in one document, rather than just relying on the combination of unclassified sources.
