1.On set A = {1, 2, 3}, relations R and S are given by R = {(1, 1), (2, 2), (3, 3), (1, 2), (2, 1)} and S = {(1, 1), (2, 2), (3, 3), (1, 3), (3, 1)}. Then,a.R ∪ S is an equivalence relationb.R ∪ S is reflexive and transitive but not symmetricc.R ∪ S is reflexive and symmetric but not transitived.R ∪ S is symmetric and transitive but not reflexiveLogin to continueOnly logged in users canattempt or see the solution.
