Correct answer: D
Correct answer: Message digest
A message digest is a hash/fingerprint generated from the message.
If even a small part of the message changes, the digest changes. This helps detect tampering.
A digital signature can also support integrity, but it is broader because it also provides authentication and non-repudiation.
So, for direct integrity verification through a fingerprint, the best answer is Message digest.
