Please do watch the complete video for in depth information in this video you ll learn about the complete detail of multiplexer what is multiplexer.
You need a combinational logic with 16 input pins 4 select lines and one output. The logical expression of the term y is as follows. The figure below shows the block diagram of a 2 to 1 multiplexer which connects two 1 bit inputs to a common destination. Logicworks multiplexers have active low enable inputs so the mux always outputs 1 when en 1.
