Which Windows utility allows you to manage disk partitions and volumes?

Correct answer: Disk Management

Option C is correct because Disk Management is the built-in Windows graphical utility that allows administrators to create, delete, format, resize, and assign drive letters to disk partitions and volumes without using the command line. Option A is wrong because the Services snap-in (services.msc) manages Windows services, not disk partitions. Option B is wrong because System Configuration (msconfig) controls startup settings, boot options, and services that load at startup, and has no disk partition management capability. Option D is wrong because Device Manager manages hardware drivers and device settings; while it can show disk devices, it does not provide partition or volume management functions.
