Question
Let A = {1, {1}, 3, 4, {5, 6}} be a set, and let B and C be the following relations on A: B = {(1, 3), (4, 1), (3, {5, 6}), ({1}, 4), ({5, 6}, {1})} C = {(1, 1), (3, 4), (4, 3), ({5, 6}, {1})The relation C is irreflexive.a.Trueb.False
Solution
False. A relation is said to be irreflexive if no element is related to itself. In relation C, we have (1,1) which means that 1 is related to itself. Therefore, relation C is not irreflexive.
