(a) Let
$D = \{-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36\}$

Determine which of the following statements are true and which are false. Provide counterexamples for those statements that are false.

(i) $\forall x \in D$, if $x$ is odd, then $x > 0$
(ii) $\forall x \in D$, if $x$ is less than 0, then $x$ is even
(iii) $\forall x \in D$, if $x$ is even, then $x \le 0$
