Question $18$

The simplified expression for the Boolean function defined by the

following Kmap is

$,x^{\text{'}}{y}^{\text{'}}z+x^{\text{'}}yz+x{y}^{\text{'}}{z}^{\text{'}}$

$,y^{\text{'}}z+x^{\text{'}}z+x^{\text{'}}{y}^{\text{'}}$

$=>,x^{\text{'}}z+x^{\text{'}}y+x{y}^{\text{'}}{z}^{\text{'}}$

$,x^{\text{'}}z+x^{\text{'}}y$

explain how x$\text{'}$z $+$ x$\text{'}$y $+$ xy$\text{'}$z$\text{'}$ is the correct option
