Explanation

B is correct because the statement contains a factual error in its characterization of the EMR8 board. The EMR8 is not a fixed multiplexer/demultiplexer - it is a reconfigurable/flexible board, meaning it can be dynamically configured rather than being locked to a fixed set of wavelengths. The "fixed" descriptor belongs to passive, non-configurable optical mux/demux hardware, which the EMR8 is not.

Why A is wrong: Accepting the statement as true would incorrectly classify the EMR8 as fixed hardware, misrepresenting its key capability - the ability to be reconfigured. This distinction matters operationally because a fixed board cannot adapt to network changes.

Memory tip: Think of the "R" concept in EMR as a hint toward Reconfigurable - if the board were truly fixed, there would be no need for the flexibility that the EMR8 is designed to provide. When you see "fixed" applied to a board with dynamic/flexible characteristics, that's your flag to mark the statement False.
