(C) relation $R$ on set $A$ is reflexive if $(a, a) \in R$ for all $a \in A$. Here,$(1, 1) 
otin R$,so $R$ is not reflexive.$A$ relation $R$ is symmetric if $(a, b) \in R \implies (b, a) \in R$. Here,$(1, 2) \in R$ but $(2, 1) 
otin R$,so $R$ is not symmetric.$A$ relation $R$ is transitive if $(a, b) \in R$ and $(b, c) \in R \implies (a, c) \in R$. Checking the elements: For $(1, 2) \in R$,there is no element $(2, c) \in R$ except $(2, 2)$. Since $(1, 2) \in R$ and $(2, 2) \in R$,we must have $(1, 2) \in R$,which is true.All other pairs $(2, 2), (3, 3), (4, 4)$ satisfy the condition trivially.Thus,$R$ is transitive.

Let $A = \{1, 2, 3, 4\}$ and let $R = \{(2, 2), (3, 3), (4, 4), (1, 2)\}$ be a relation on $A$. Then $R$ is
