Which of the following descriptions about ROADM boards are wrong? (Multiple choice)

The correct answer is A. RMU9 can add wavelengths of 9 signals. Its add-wave port can be used with an OTU board with B. WSM9 realizes the dynamic and configurable wavelength division function of any wavelength to C. WSD9 realizes the dynamic and configurable multiplexing function of any wavelength to any port. See the full explanation below for the reasoning.
