Which of the following commands can be used to create a USB storage media from a disk image?

The correct answer is B. dd. The dd command is a powerful utility frequently used to create bootable USB storage media by copying a disk image (like an ISO file) directly onto the USB device in a raw, byte-for-byte fashion.

Why each option

The `dd` command is a powerful utility frequently used to create bootable USB storage media by copying a disk image (like an ISO file) directly onto the USB device in a raw, byte-for-byte fashion.

Agdisk

`gdisk` is a GPT (GUID Partition Table) partitioning tool, used for creating and managing disk partitions, not for writing disk images.

BddCorrect

The `dd` command (data duplicator) is ideal for copying raw data from an input file (like a disk image) to an output device (like a USB drive). This process creates a bit-for-bit clone of the image, making the USB drive bootable if the image is designed as such.

Ccc

`cc` is typically the C compiler command and has no function related to creating USB storage media from disk images.

Dfdisk

`fdisk` is a disk partitioning utility for MBR (Master Boot Record) formatted disks, used to create and manage partitions, not for writing disk images.

Emount

`mount` is used to attach a filesystem from a storage device to a directory in the filesystem hierarchy, it does not create bootable media.
