Match $\text{List I}$ with $\text{List II}$
Let $R_1=\{(1,1), (2,2), (3,3)\}$ and $R_2=\{(1,1), (1,2), (1,3), (1,4)\}$
$\begin{array}{llll} & \text{List I} & & \text{List II} \\ (A) & R_1 \cup R_2 & (I) & \{(1,1), (1,2), (1,3), (1,4), (2,2), (3,3) \} \\ (B) & R_1 – R_2 & (II) & \{(1,1)\} \\ (C) & R_1 \cap R_2 & (III) & \{(1,2), (1,3), (1,4) \} \\ (D) & R_2 – R_1 & (IV) & \{(2,2), (3,3)\} \end{array}$
Choose the correct answer from the options given below:
