Answer: B
Key verification is a process in which keying-in is repeated
by a separate individual using a machine that compares the
original entry to the repeated entry. Sequence check refers
to the continuity in serial numbers within the number range
on documents. A check digit is a numeric value that has been
calculated mathematically and added to data to ensure that
the original data have not been altered or an incorrect but
valid value substituted. Completeness checks ensure that all
the characters required for a field have been input.
