$.$The adder$-$subtractor circuit, see the Figure, has the following values for mode input $M$ and data inputs A and $B$

$M(0),A(1000)$ and $B(1001)$

Determine the values of the four SUM outputs, the carry C$,$ and overflow V

$\frac{?}{\text{S}\text{U}\text{M}}(0001),C(1),V(1)$

SUM $(1101),$ C$(0),$ V$(0)$

SUM $(1101),$ C$(0),$ V$(1)$

SUM $(1100),$ C$(1),$ V$(0)$
