Selected Answer: B
The command that can be used to create a USB storage media from a disk image is 'dd'. Option B is the correct answer. The 'dd' command is a utility for copying data from one location to another. It can be used to create a USB storage media from a disk image by copying the contents of the disk image to the USB device. To create a USB storage media from a disk image using 'dd', you can use the following command: sudo dd if=image_file of=/dev/sdb bs=4M This command will copy the contents of the disk image 'image_file' to the USB device '/dev/sdb' using a block size of 4 megabytes. Note: Make sure to replace 'image_file' with the path to the disk image and '/dev/sdb' with the device name of the USB storage media. It is important to specify the correct device name, as using the wrong device name can result in data loss.
