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.

We are NOT mind readers!
