Why each option
A password-protected screen saver locks the workstation after a period of inactivity, requiring re-authentication before access is granted again.
When a user leaves a workstation unattended, a password-protected screen saver automatically locks the session after the configured idle timeout, preventing any unauthorized person with physical access from using the system without valid credentials.
A screen saver has no effect on network-level Denial of Service attacks because DoS targets service availability over the network, not local workstation login state.
Social engineering attacks manipulate people psychologically to divulge information or grant access; a screen saver lock cannot stop a user from being deceived into unlocking their own machine.
A back door attack exploits a hidden access mechanism already present in software or the OS; a screen saver lock does not remove or block existing back doors installed on the system.
