Which fields are mandatory for a non-unique identifier inquiry?

The correct choice includes a comprehensive set of fields that are mandatory for conducting a non-unique identifier inquiry. Specifically, these fields—ORI (Originating Agency Identifier), AGE (Age), SEX (Sex), RAC (Race), EYE (Eye color), HAI (Hair color), HGT (Height), and WGT (Weight)—provide essential data that ensures accurate identification in the inquiry process. Each of these elements serves to narrow down potential matches in the databases being searched.

For instance, the ORI helps identify the agency making the inquiry, while personal attributes like AGE, SEX, and RAC provide crucial demographic details about the individual in question. Additionally, physical characteristics such as EYE, HAI, HGT, and WGT enable further refinement, which is particularly important in cases where there may be multiple individuals with similar names. By including this full set of identifiers, the inquiry is more likely to yield relevant and accurate results, reducing the chances of misidentification.

The other options contain fewer fields, which can limit the effectiveness of the inquiry. Incomplete information might not adequately distinguish one individual from another, especially in databases with large populations.
