Which of the following protocols uses a combination of public key and symmetric encryption to provide communication privacy, authentication, and message integrity for secure browsing on the Internet?

SSL combines asymmetric (public key) cryptography to authenticate the server and securely exchange a session key, then uses that symmetric session key for efficient encrypted communication - precisely matching the description of combining both encryption types for privacy, authentication, and message integrity in secure web browsing (HTTPS).

MS-CHAP v2 is a Microsoft challenge-response authentication protocol used in VPN and dial-up scenarios; it does not provide general browsing encryption using a public/symmetric hybrid model.

EFS (Encrypting File System) is a Windows feature for encrypting files on disk; it is not a network communication protocol and does not facilitate secure Internet browsing.

WEP (Wired Equivalent Privacy) is a deprecated wireless network encryption protocol for Wi-Fi; it does not provide browser-level communication privacy or use a public key and symmetric hybrid approach.
