Based on the following PAL implementation of a multi-input (X,Y,Z) multi-output (F1,F2,F3) combinational system, possible descriptions of outputs F1, F2 and F3 are: F1 F2 F3 F3-YZ+XY F3-2m(1,4,5) F1-YZ+XY F1-m(3,45,7) F2-m(1.2.5,6,7) F1-YZ+XY Only a) is true None of the above are true a).b),c) are all true. F2 -YZ+YZ'+XY
