Comprehensive and Detailed Step-by-Step Explanation:Transposition and transcription errors occur when characters or numbers are accidentally swapped or misentered during data entry.
* Option A (Incorrect):Duplicate checks ensure that the same record is not entered twice but do not specifically detect transposition or transcription errors.
* Option B (Incorrect):Completeness checks ensure that all required data is entered but do not validate data accuracy.
* Option C (Incorrect):Sequence checks verify that records follow a logical sequence but do not catch errors within individual data entries.
* Option D (Correct):Acheck digitis an additional number generated through an algorithm (e.g., Luhn algorithm for credit cards) that helps detect errors such as transpositions (e.g., swapping digits 45 # 54) and transcriptions (e.g., mistyping 8 as 3).
