Which of the following is a quality control activity?

Quality control in this context means regularly monitoring conditions that could affect the accuracy and reliability of test results. Recording the refrigerator temperature daily directly protects specimen integrity by ensuring stored samples stay within the required temperature range, and the log provides a traceable record that any deviations are spotted and corrected promptly. The other tasks are important for operations—checking expiration dates is about using good materials, documenting centrifuge maintenance is about keeping equipment in good working order, and filling out time sheets is administrative. But they do not continuously monitor a condition that directly impacts sample quality in the same way daily temperature checks do, making the refrigerator temperature record the core quality control activity here.
