The output expression for an AND$-$OR$-$Invert circuit having one AND gate with inputs A$,$ B$,$ C and another AND gate with inputs $D,E,F$ is

Select one:

A$.(\frac{?}{\text{b}\text{a}\text{r}}(A)\frac{+}{b}ar(B)\frac{+}{b}ar(C))(\frac{?}{\text{b}\text{a}\text{r}}(D)\frac{+}{b}ar(E)\frac{+}{b}ar(F))$

B$.(A+B+C)(D+E+F)$

C$.\frac{?}{\text{b}\text{a}\text{r}}(A)\frac{+}{b}ar(B)\frac{+}{b}ar(C)\frac{+}{b}ar(D)\frac{+}{b}ar(E)\frac{+}{b}ar(F)$

D$.$ ABC$+$DEF
