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

gdisk is a partition table editor for GPT-formatted disks and has no capability to write disk images to a block device.

dd reads from an input source (if=) and writes byte-for-byte to an output destination (of=) at the block level, bypassing filesystem abstraction. A command such as 'dd if=image.iso of=/dev/sdX bs=4M' writes the entire disk image directly to the USB storage device, preserving the exact partition layout, boot records, and filesystem structures required to produce a bootable or functional USB drive.

cc is the C language compiler front-end and has no functionality related to disk image writing or block device access.

fdisk is a partition table editor for MBR-formatted disks and cannot write raw disk images to a storage device.

mount attaches an already-formatted filesystem to the directory tree and cannot copy a disk image onto a raw block device.
