Which of the following is a command that will display the syntax for a Windows CLI command?

The correct answer is A) help.

In the Windows Command Line Interface (CLI), the `help` command is used to display information about various commands, including their syntax and options. While option B (`robocopy /?`) can also provide syntax information for a specific command, the general command to display help for commands is `help`. Options C and D are not applicable in Windows CLI.
