This uniqueness is achieved through the use of cryptographic algorithms that generate a signature based on the content of the message and the sender's private key, making it mathematically improbable for two different messages to produce the same signature.
Option D, "is validated when data are changed," refers more to the property of digital signatures being able to detect alterations to the signed data rather than a characteristic of the signature itself.
