    The way I look at it you are using your input bits to be added as the address bits of the multiplexer, which is A and B. C is the carry input from anywhere, and it is assumed that you have an inverted carry input which is C' (or maybe add one inverter to do the job). With the two 4X1 multiplexer, you have addressable selections for the output Carry and output sum. This circuit can work based on my analysis.
