What does CODIS stand for?

The correct answer is "Combined DNA Index System." CODIS is a national database that enables law enforcement agencies to compare DNA profiles from crime scenes with those from known offenders and missing persons. It consolidates DNA data from various jurisdictions to facilitate investigations and aid in solving crimes. By providing a platform for storing and sharing DNA information, CODIS plays a vital role in forensic science and public safety.

The other choices do not accurately represent what CODIS stands for. For instance, "Criminal Online Database of Information Systems" and "Comprehensive Online Data Integration System" do not specifically refer to DNA or the purpose of the database, while "Criminal Offender Database and Information System" does not capture the critical aspect that CODIS focuses on the combination of DNA profiles for matching rather than just offender information.
