Question $30($Mandatory$)(2$ points$)$

Which Boolean equation results from this Karnaugh map?

$\backslash$table$[[,,$C$],[\frac{?}{\text{b}\text{a}\text{r}}\frac{A}{b}ar(B),1,],[$A B$,,1],[$A B$,1,1],[$A $\frac{?}{\text{b}\text{a}\text{r}}(B),1,]]$

$(AB)+(\frac{?}{\text{b}\text{a}\text{r}}(B)C)+(\frac{?}{\text{b}\text{a}\text{r}}\frac{B}{b}ar(C))$

$(AB)+(BC)+(\frac{?}{\text{b}\text{a}\text{r}}\frac{B}{b}ar(C))$

$(AC)+(\frac{?}{\text{b}\text{a}\text{r}}\frac{A}{b}ar(B))+(\frac{?}{\text{b}\text{a}\text{r}}\frac{B}{b}ar(C))$

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

Question $28($Mandatory$)(2$ points$)$

The simplified form of $x=AC\frac{+}{b}ar(c)(A+B)$ is

$x=AC+B$

$x\frac{?}{b}=ar(c)+AC$

$x=AC+\frac{B}{b}ar(c)$

$x=A+\frac{B}{b}ar(c)$
