Selected Answer: A
This method involves creating a digital signature by encrypting a hash of the message with the sender's private key. The recipient can then use the sender's public key to decrypt the signature and compare it with a newly computed hash of the received message. If the two hashes match, it indicates that the message has not been modified in transit. Digital signatures provide integrity and authenticity verification for email messages.
