In MS-DOS, the maximum length of a command, including any optional parameters, is limited to 127 characters. This includes the command itself and any parameters or options that follow it. MS-DOS commands are entered at the command prompt and are typically short, but they can include various options and parameters to modify their behavior.

Therefore, the correct answer is Option C: 127 characters.
