Which of the following statements is TRUE regarding the confidentiality provided by encryption?

The statement indicating that only the intended recipient can read the email accurately describes the primary function of encryption. Encryption transforms data into a format that is unreadable to anyone who does not possess the correct decryption key. This means that even if an email is intercepted during transmission, unauthorized individuals, including those who might gain access to the server or the network, would not be able to decipher the content without the encryption key. Therefore, the intended recipient, who has the proper means to decrypt the message, is the only individual who can access the information in its original, readable form. This ensures that the confidentiality of the communication is preserved between the sender and the specified recipient.

In contrast, the other statements do not adequately reflect how encryption works or its role in maintaining privacy throughout the communication process. It is crucial for these points to be clearly understood to appreciate the importance of encryption in safeguarding confidential information.
