To send someone a secure e-mail message using PGP, you should use which of the following?

EXPLANATION

Pretty good privacy (PGP) can be used to send messages confidentially. For this, PGP combines symmetric-key encryption and public-key encryption. The message is encrypted using a symmetric
encryption algorithm, which requires a symmetric key. Each symmetric key is used only once and is also called a session key. The message and its session key are sent to the receiver. The session key must be sent to the receiver so they know how to decrypt the message, but to protect it during transmission, it is encrypted with the receiver's public key. Only the private key belonging to the receiver can decrypt the session key.
