B Correct answer
Explanation

In Unix/Linux systems, the 'man' command displays manual pages for commands. 'man cp' shows the complete documentation for the cp command, including usage, options, and examples. The 'help' command is typically a shell built-in for shell commands, not external commands like cp. 'cp?' and 'help' without arguments are not valid help commands.

To get help about the command "cp", you can use the "man" command, which stands for "manual". The correct answer is B) "man cp".

The "man" command provides you with the manual pages for a specific command. It gives you detailed information about how to use the command, its options, and examples.

You can navigate through the manual page using the arrow keys or the "Page Up" and "Page Down" keys.

Option A) "help cp" is incorrect because the "help" command is used to get help about built-in shell commands, not external commands like "cp".
