Solution

The correct option is B Hard Disk
Hard disks store data in magnetic strips. When a strong magnet is kept near the hard disk, it can damage the data and corrupt the hard disk. So, we should make sure not to keep magnets near PCs and mobile phones. In fact, keeping mobile phone over PC is also not recommended as both consists of magnets.
