The correct choice pertains to the system utilized for explaining why a traveler is referred to Secondary. CSIS, or the Customs and Border Protection's Customs Security and Information System, plays a key role in the processing and analysis of traveler information. This system aggregates data that helps officers identify potential security threats and incidents that may warrant further examination or questions for travelers passing through border checkpoints.

When a traveler is referred to Secondary, it typically indicates that additional scrutiny is needed beyond the initial inspection. This may arise from discrepancies in the traveler's documentation or alerts based on automated checks against various databases. CSIS supports this process by providing relevant information and context to officers, aiding them in making informed decisions about the secondary inspection.

The other systems have different functionalities. TECS, for instance, is primarily focused on processing and tracking immigration and border-related data but does not specifically explain referral reasons. NCIC is a criminal justice database that assists law enforcement with information on criminal activities but is not focused on traveler processing. TSDB, or the Terrorist Screening Database, is designed for identifying individuals associated with terrorism and is used for security screenings rather than the general context of secondary referrals in border management.
