The logically equivalent proposition of $p \Leftrightarrow q$ is
A$(p \wedge q) \vee (p \wedge q)$
B$(p \Rightarrow q) \wedge (q \Rightarrow p)$
C$(p \wedge q) \vee (q \Rightarrow p)$
D$(p \wedge q) \Rightarrow (q \vee p)$
Solution
(b)$(p \Rightarrow q) \wedge (q \Rightarrow p)$ means $p \Leftrightarrow q$.
