Answer: (B)

This item tests which Department Order established the National Reference Laboratories. The Department Order numbered DO 393-E s. 2000 is the one that created the NRLs, formalizing a national network of reference laboratories under the Department to support standardized testing, quality assurance, and reference services across facilities. It defines the NRLs’ roles in confirmatory testing, method development, distribution of reference materials, and coordination of external quality assessment. The other Department Orders listed refer to different directives or timeframes and do not establish the NRLs, so they do not fit the specific action of creating the NRLs.
