To get help about the command "cp" in the terminal, you can use the "man" command followed by the command you want help with. The correct answer is B.
Option A) help cp - This option is incorrect because the "help" command is used to get help about built-in shell commands, not external commands like "cp".
Option B) man cp - This option is correct. The "man" command is used to display the manual pages for a command. By typing "man cp" in the terminal, you will get detailed information about the "cp" command, including its usage, options, and examples.
Option C) cp ? - This option is incorrect because typing "cp ?" would not give you any help or information about the "cp" command. The question mark is not recognized as a command or argument in this context.
Option D) f2 cp - This option is incorrect because typing "f2 cp" would not give you any help or information about the "cp" command. "f2" is not a recognized command or argument in this context.
The correct answer is B. Using the "man" command followed by the command you want help with, such as "man cp", will provide you with the necessary information about the "cp" command.
