D Correct answer
Explanation

Windows/DOS commands typically support 'help ' or ' /?' syntax for help information. The '?' is a standard help flag in Windows command-line utilities. Unix systems use 'man' instead. The question asks about the pattern, and both 'help dir' and 'dir ?' represent Windows-style help approaches.
