Which statement best describes data integrity?

Which statement best describes data integrity?

• A. Not disclosed to unauthorized users
• B. Data consistency
• C. Unable to deny the action
• D. Only authorized users

Answer: (B)

Data integrity means keeping data accurate, reliable, and unaltered except by legitimate updates, so it stays consistent over time. The statement that best describes this is data consistency, since it directly reflects the idea that data remains correct and uncorrupted across storage and transmission, with checksums, hashes, and audit trails used to verify it. Not disclosing data to unauthorized users relates to confidentiality, not whether data remains accurate. The idea of not being able to deny an action points to non-repudiation, and restricting access to authorized users concerns access control rather than the data’s truthfulness or consistency.
