A is corrent because it provides for maintenance of documentation of the various quality control policies and procedures—it is all encompassing. 
B is incorrect because the monitoring quality control element relates to assuring that the various quality control elements are relevant, adequate, and operating effectively.  A file of minutes of staff meetings would not involve monitoring. 
C is incorrect because documentation of demonstration of compliance with peer review directives would not be considered part of the element of monitoring quality control. 
D is incorrect because updated personnel files relates more directly to the human resources quality control standard.
