Equation $Y$ has two possible reduced forms. Select the correct two from the list below. You nan

implement either one of them in your final design.

$Y(A,B,C,D)=A^{\text{'}}{B}^{\text{'}}D+C^{\text{'}}D+BD$

$Y(A,B,C,D)=A^{\text{'}}{B}^{\text{'}}D+C{D}^{\text{'}}+B{D}^{\text{'}}$

$Y(A,B,C,D)=A^{\text{'}}{B}^{\text{'}}D+B{C}^{\text{'}}+BD$

$Y(A,B,C,D)=A^{\text{'}}{B}^{\text{'}}D+B^{\text{'}}C+B{D}^{\text{'}}$
