Selected Answer: C
C. The web browser encrypts the PremasterSecret with the server's public key. During a TLS (Transport Layer Security) session, after the web browser generates a random PremasterSecret, it encrypts this PremasterSecret using the server's public key. This encrypted PremasterSecret is then sent to the server. The server, which possesses the corresponding private key, decrypts the PremasterSecret. Both the client and the server use the PremasterSecret, along with additional data, to generate the session keys that will be used for encrypting the rest of the session’s data.
