Let set X = {1, 2, 3} and a relation R is defined in X as : R = {(1, 3), (2, 2), (3, 2)}, then minimum ordered pairs which should be added in relation R to make it reflexive and symmetric are
A. {(1, 1), (2, 3), (1, 2)}
B. {(3, 3), (3, 1), (1, 2)}
C. {(1, 1), (3, 3), (3, 1), (2, 3)}
D. {(1, 1), (3, 3), (3, 1), (1, 2)}
Answer:C
