If $A,B\:and\: C$ are three finite sets, then $[(A\cup B)\cap C]'$ = ?

$\begin{array}{1 1} A' \cup B' \cup C' \\A'\cap B'\cap C' \\ A'\cap B'\cup C' \\ A\cap B\cup C \end{array}$

Can you answer this question?

Toolbox:
• $(A\cup B)'=A'\cap B'$
• $(A\cap B)'=A'\cup B'$
$[(A\cup B)\cap C]'=(A\cup B)'\cup C'$
$=A'\cap B'\cup C'$
