Which of the following statements is $NOT$ logically equivalent to $\left( {p \to \sim p} \right) \to \left( {p \to q} \right)$?
A
$\left( {p \to p} \right) \to \left( {p \to \sim p} \right)$
B
$q \to \left( {p \to q} \right)$
C
$\left( {q \to \sim p} \right) \to \left( {q \to p} \right)$
D
none of these
