In the interest of national security, the TSC enters records for individuals suspected of what?

The correct choice highlights that the Terrorist Screening Center (TSC) specifically focuses on individuals suspected of engaging in terrorist activities. The TSC is a critical component of the U.S. government's efforts to enhance national security by identifying individuals who may pose a threat due to their involvement in terrorism, either domestically or internationally. This specialized screening allows for more focused intelligence and monitoring of potential terrorists, which is vital to preventing attacks and maintaining public safety.

Other options, while they may involve serious criminal activities, do not fall under the TSC's specific mandate. Felony charges, immigration issues, and financial crimes are typically handled by various law enforcement agencies and do not directly pertain to the broader national security concerns that the TSC addresses through its focus on terrorism-related threats.
