Answer: A
A demultiplexer is called a data distributor because the input is distributed to one of the outputs.
A demultiplexer has one data input, several outputs and select lines. The select code decides which output receives the input data, so a single line of data can be distributed to any of several destinations.
Selecting one of several inputs for a single output is what a multiplexer (data selector) does. 'The output is distributed to one of the inputs' reverses the direction of data flow, and buffering is not what the name refers to.
