Data Verification is best described as which of the following?

• A. Verifies that input data is within the expected range
• B. Ensures data is stored securely
• C. Checks that code runs correctly
• D. Validates that data is correct and accurate

Answer: (D)

Data verification focuses on making sure the data is true, precise, and trustworthy. It goes beyond just being within a plausible range or that something processed without errors; it checks that the values reflect the actual source and are consistent and correct. The option stating that data is valid and accurate best captures this idea, because it emphasizes the data’s correctness itself. In contrast, checking input within a range is about plausibility, storing data securely is about protection, and ensuring code runs correctly is about software behavior, not data quality. For example, a birth date and a listed age should both align; a range check might say the age is plausible, but verification ensures the age actually matches the birth date. Data verification, then, is about data being correct and accurate.
