Which of the following combinational circuit gives the Boolean expression for DIFFERENCE of a full subtractor?

 

I give up.
Which is it?

Is this homework?

 

Not only do you want someone to answer your homework question for you, but you don't even want to be bothered with indicating what the various signals -- {x, y, z} -- represent?

How about starting with the Truth Table for a full subtractor? Or are we supposed to provide that, too?

 

Hi,

The answer is simple. The answer is: it is either A, B, C, or D.
Once we get more info we might be able to narrow it down

 

It would also help if you indicated which input to the MUX corresponds to which state of the select signal.
