The dual of the statement pattern $\sim \mathrm{p} \wedge(\mathrm{q} \vee \mathrm{t})$ is (where $t$ is a tautology and $c$ is a contradiction)
  1. $p \vee(q \wedge c)$
  2. $\sim \mathrm{p} \vee(\mathrm{q} \wedge \mathrm{t})$
  3. $\sim \mathrm{p} \vee(\mathrm{q} \wedge \mathrm{c})$
  4. $p \vee(q \wedge t)$

Solution

dual of $\sim p \wedge(q \vee t)$ is $\sim p \vee(q \wedge c)$
