In relation to data integrity, what does the CRC ensure?

• A. Real-time data publication.
• B. Financial reporting accuracy.
• C. Legal compliance of contracts.
• D. Accurate, complete, timely documentation.

Answer: (D)

The main idea is that a CRC (Cyclic Redundancy Check) detects data errors to protect data integrity. By adding a checksum derived from the data, any corruption that occurs during storage or transmission can be detected when the data is read again and the checksum recalculated. This capability helps ensure that the information recorded in trial documentation stays accurate, complete, and available in a timely manner, because corrupted entries can be identified and corrected before they are used or published. Real-time publication, financial reporting accuracy, and legal compliance are important on their own, but CRCs specifically address detecting unintended data changes, not guaranteeing publication speed or domain-specific compliance.
