Which of these is the dual of the Boolean expression (P∧Q)∨(R∧0)(P \land Q) \lor (R \land 0)(P∧Q)∨(R∧0)?
(P∨Q)∧(R∨1)(P \lor Q) \land (R \lor 1)(P∨Q)∧(R∨1)
(P∧Q)∨(R∧1)(P \land Q) \lor (R \land 1)(P∧Q)∨(R∧1)
(P∨Q)∧(R∨0)(P \lor Q) \land (R \lor 0)(P∨Q)∧(R∨0)
(P∨Q)∨(R∧1)(P \lor Q) \lor (R \land 1)(P∨Q)∨(R∧1)
