\bar{A B} + \bar{A} \bar{B} \cdot (C + \bar{C})

\bar{A B C} + \bar{A B} \bar{C} + \bar{A} \bar{B C} + \bar{A} \bar{B} \bar{C} \cdot (D + \bar{D})

\bar{A B C D} + \bar{A B C} \bar{D} + \bar{A B} \bar{C D} + \bar{A B} \bar{C} \bar{D} + \bar{A} \bar{B C D} + \bar{A} \bar{B C} \bar{D} + \bar{A} \bar{B} \bar{C D} + \bar{A} \bar{B} \bar{C} \bar{D}

B + \bar{B} = 1

So the given expression should

simplify to

\bar{A}
