Match List-I with List-II and choose the correct answer from the code given below :
$\begin{array}{|c|c|c|c|} \hline & \textbf{List I} & & \textbf{List II} \\ \hline (a) & Equivalence & (i) & p \Rightarrow q \\ \hline (b) & Contrapositive & (ii) & p \Rightarrow q; q \Rightarrow p \\ \hline (c ) & Converse & (iii) & p \Rightarrow q: \sim q \Rightarrow \sim p \\ \hline (d) & Implication & (iv) & p \Leftrightarrow q \\ \hline \end{array}$
(a) - (iv)
(b) - (iii)
(c) - (ii)
(d) - (i)

Option (d)
$p\rightarrow q$
Equivalence : $p\rightarrow q\,\wedge\,q\rightarrow p $
Contrapositive : $\neg q\rightarrow \neg q$
Converse : $q\rightarrow p$
Implication : $p\rightarrow q$
$D\,)$ must be the answer
