What is the primary purpose of marking classified information?

The primary purpose of marking classified information is to provide clear information about the classification and the dissemination restrictions associated with that information. This marking helps ensure that anyone who handles the information understands its sensitivity level and the specific protocols that need to be followed in order to protect it. Clear marking indicates who is authorized to access the information, how it should be stored or transmitted, and when or if it is to be declassified. This plays a crucial role in maintaining national security and preventing unauthorized access or inadvertent disclosure.

The other options do not capture the main intent behind the marking of classified information. While visibility is important, the primary goal is informing handlers about the classification and its dissemination protocols, rather than merely making the information visible. The options that reference confusion or simplification do not align with the objectives of marking, which is fundamentally aimed at clarity and operational security in handling classified materials.
