Which of the following is a benefit of setting up a computer to receive automatic updates from the OS vendor?

A (Arranges the hard drive files in order) describes disk defragmentation, which is a separate maintenance task and not the primary function of OS updates.

B (Restores missing files that were lost or deleted) describes data recovery or backup restoration, not a function of routine OS updates.

C (Keeps the software current and applies security patches) is a primary benefit of automatic OS updates, as these updates deliver bug fixes, new features, and, most critically, security patches that address vulnerabilities. Applying these patches promptly helps protect the system from exploits.

D (Provides the latest virus definitions to keep the computer safe) is typically a function of antivirus software, not the operating system's automatic updates for itself.
