C Correct answer
Explanation

A hard disk is a non-volatile storage device used to store large amounts of data permanently. Unlike RAM or Cache, which lose their data when power is removed, the hard disk keeps files and programs safe for long-term use. EPROM is used for firmware, but not for general long-term data storage like a hard drive.
