$f(A, B, C, D) = \pi M(0,1,3,4,5,7,9,11,12,13,14,15)$ is a maxterm representation of a Boolean function $f (A, B, C, D)$ where $A$ is the $MSB$ and $D$ is the $LSB$. The equivalent minimized representation of this function is
- $(A +\overline{C}+D) (\overline{A}+B+D)$
- $A\overline{C}D + \overline{A}BD$
- $\overline{A}C\overline{D}+A\overline{B}C\overline{D}+A\overline{B} \: \overline{C} \: \overline{D}$
- $(B+\overline{C}+D) (A+\overline{B}+\overline{C}+D) (\overline{A}+B+C+D)$
