The output of the circuit: Y = -X For don't cares, the outputs are set to O's. Use a multiplexer to implement only the most-significant bit (MSB) of the circuit output. From the list below, select the correct set of multiplexer inputs. Draw (on paper) fully-labeled circuit diagram. (Include complete solution in the test exam PDF file). (a) D, 1, 1, 7,0,0,0,0 (b) D, D,0,0,0,1,0,1 MacBook Air
