Final answer:
The correct command for copying information in Linux is the cp command. It can be used to copy files or directories, and the -r option is used to copy directories and their contents.
Step-by-step explanation:
The correct command that James can use to copy blocks of information from one device to another in Linux is the cp command. This command stands for 'copy' and is used to copy files or directories.
For example, to copy a file named 'file1.txt' from the current directory to another directory named 'destination', James can use the command:
cp file1.txt destination/
If James wants to copy an entire directory and its contents to another location, he can use the -r option with the cp command. For instance, if he wants to copy a directory named 'folder1' and all its files and subdirectories to the 'destination' directory, he can use the command:
cp -r folder1/ destination/
