The testing facility must have archives for long$-$term storage of raw data. There also must be a quality assurance unit $($QAU$)$ for monitoring operations that are associated with the quality system. Which statement is most true about both areas of responsibility?

A single person is sufficient to serve in both roles if resources are limited$.$

The personnel in both areas only operate during the weekdays, differing from study direction or animal care responsibilities.

The QAU takes care of both roles because they audit the final report against the raw data.

A member of the QAU cannot be the archivist because they must audit archiving procedures.
