What are potential consequences of improperly marking classified information?

Improperly marking classified information can lead to significant negative outcomes, primarily because accurate marking is crucial for maintaining the integrity and security of sensitive information. The correct response highlights the potential legal penalties that can arise from mishandling classified data, including disciplinary action, termination of employment, or even criminal charges, depending on the severity of the breach. Additionally, improperly marked information can lead to unintentional disclosures, resulting in compromise of sensitive data that can endanger national security. This loss of control over classified materials can undermine intelligence operations, expose vulnerabilities, and potentially harm individuals or assets associated with national security, highlighting the critical importance of adhering to proper marking protocols.

The other choices do not align with the consequences of improper marking; instead, they suggest improvements or benefits that are contrary to the risks associated with failing to correctly mark classified information.
