A simple application of De Morgan's laws reveals the solution to this problem. The original equation applies an and function to its inputs and then negates the output, yielding it equivalent to...

¬ ( A ∧ B ) ⇔ ¬ A ∨ ¬ B \lnot (A \ \land \ B) \Leftrightarrow \lnot A \lor \lnot B

Therefore, the answer is A.

A B A’ B’ Y 0 0 1 1 1 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0

so the result is equal to logic gate 0
