A validity check ensures that the data entered into the system meets a specific set of criteria, such as the correct format for a phone number, zip code, or area code. If a validity check had been run when the new client contact information was entered, the error would have been caught and corrected before the block of contacts became useless to the company. The other options (limit check, sequence check, and record count) are unlikely to catch this type of error.
