(C) Given the set $A = \{2, 4, 6, 8\}$ and the relation $R = \{(2, 4), (4, 2), (4, 6), (6, 4)\}$.$A$ relation $R$ is symmetric if for every $(a, b) \in R$,we have $(b, a) \in R$.Check the elements of $R$:$1$. For $(2, 4) \in R$,we have $(4, 2) \in R$.$2$. For $(4, 2) \in R$,we have $(2, 4) \in R$.$3$. For $(4, 6) \in R$,we have $(6, 4) \in R$.$4$. For $(6, 4) \in R$,we have $(4, 6) \in R$.Since for all $(a, b) \in R$,the corresponding $(b, a)$ is also in $R$,the relation $R$ is symmetric.

Let $A = \{2, 4, 6, 8\}$. $A$ relation $R$ on $A$ is defined by $R = \{(2, 4), (4, 2), (4, 6), (6, 4)\}$. Then $R$ is
