Show answer & explanation
Correct answer: B
The circuit begins with a NAND gate outputting (AB)' and a NOR gate outputting (C+D)'. These signals combine with inputs E and F in three AND gates to produce terms (AB)'E, EF, and (C+D)'F.
The final gate is a NOR operation on these three terms, creating the expression ((AB)'E + EF + (C+D)'F)'. Applying De Morgan's laws simplifies this to (E' + ABF')(C + D + F').
