Which data state would be most likely to use digital signatures as a security protection mechanism?
The correct answer is A. Data in use. Digital signatures are cryptographic mechanisms used to verify the authenticity and integrity of data and to provide non-repudiation. They are most applicable to data in use-data that is actively being created, accessed, processed, or signed (e.g., signing a contract, verifying…

Explanation
Digital signatures are cryptographic mechanisms used to verify the authenticity and integrity of data and to provide non-repudiation. They are most applicable to data in use-data that is actively being created, accessed, processed, or signed (e.g., signing a contract, verifying software before execution, or authenticating a document). While encryption protects data in transit and at rest, digital signatures are specifically applied at the point of active use to confirm who created or approved the data and that it has not been altered.
