(C) Given the set $A = \{1, 2, 3, 4\}$ and the relation $R = \{ (1, 1), (2, 3), (3, 4), (4, 2) \}$.First,we check if $R$ is a function. Since every element in the domain $A$ has a unique image in the codomain $A$,$R$ is a function.Next,we check if $R$ is one-to-one. The images are $\{1, 3, 4, 2\}$. Since all images are distinct,$R$ is a one-to-one function.Finally,we check if $R$ is onto. The range of $R$ is $\{1, 2, 3, 4\}$,which is equal to the codomain $A$.Since the range equals the codomain,$R$ is an onto function.Therefore,the correct statement is that $R$ is an onto function.

Let $A = \{1, 2, 3, 4\}$ and $R : A \to A$ be the relation defined by $R = \{ (1, 1), (2, 3), (3, 4), (4, 2) \}$. The correct statement is
