Selected Answer: A
Encryption is the technique that would protect the confidentiality of information sent in email messages. Encrypting email messages ensures that the content is scrambled in such a way that only authorized parties with the proper decryption key can understand the original information. This is particularly important for protecting sensitive or confidential data during transmission.
