(a) Connect the outputs of three 3-state buffers together, and add additional logic to implement the function

Assume that C, D, and D are data inputs to the buffers and A and B pass through logic that generates the enable inputs.

(b) Is your design in part (a) free of three-state output conflicts? If not, change the design to be free of such conflicts.
