Explanation

S-RPC (Secure Remote Procedure Call) directly addresses remote code execution by adding authentication to the RPC mechanism - the very system by which code is invoked on remote machines - ensuring only authorized callers can trigger remote procedures. TACACS and RADIUS are both AAA (Authentication, Authorization, Accounting) frameworks, but they control network access (device login, VPN, dial-in), not whether a remote procedure or code block can be executed. CHAP is a challenge-response protocol used to verify identity over PPP links, again focused on connection authentication rather than governing code execution on a remote host.

Memory tip: RPC = Remote Procedure Call - it's literally the mechanism for running code on another machine. The "S" in S-RPC just means it's the secured version. If the question involves executing code remotely, lock onto the word "Procedure" as your clue.
