Explanation
Reconciliation routines are methods to verify the integrity of data by comparing the input and output of a process or a system. They can detect errors, omissions, duplications or unauthorized modifications of data. They are more directly related to data integrity than the other options, which are more concerned with data definition, logging or access control.
