Answer: B
A check digit is a numeric value that is calculated
mathematically and is appended to data to ensure that the
original data have not been altered or an incorrect, but
valid, value substituted. This control is effective in
detecting transposition and transcription errors. A range
check is checking data that matches a predetermined range of
values. A validity check is programmed checking of the data
validity in accordance with predetermined criteria. In a
duplicate check, new or fresh transactions are matched to
those previously entered to ensure that they are not already
in the system.
