Which behaviors might indicate a risk for potential espionage during the PERSEC evaluation?

This answer is rooted in the understanding of how certain behaviors can be indicative of potential risks related to espionage. Unexplained wealth or sudden lifestyle changes often raise red flags, as they may suggest that an individual is receiving compensation or benefits that are not accounted for through their legitimate earnings. Additionally, associations with foreign nationals can be concerning, particularly if those individuals represent countries of interest to national security. These connections may raise questions about whether an individual is being influenced or may have access to sensitive information that could be exploited.

Frequent tardiness, disagreements with management, or being overly cautious during evaluations do not inherently suggest espionage risk. These behaviors may stem from personal issues or workplace dynamics but lack the direct connections to the security concerns that unexplained wealth or foreign associations imply. Therefore, option B is the most relevant in the context of identifying behaviors that could indicate a potential risk for espionage during a Personnel Security evaluation.
