4 votes 4 votes The best way to solve this question is by taking counter example EDIT : I forgot to write (a,a) in set S it's from transitive property (a,c),(c,a) so (a,a) should be present in S [ Jiren ] answered Aug 23, 2022 • edited Aug 23, 2022 by [ Jiren ] [ Jiren ] comment Share Follow See 1 comment See all 1 1 comment reply Overflow04 commented Aug 23, 2022 reply Follow Share thanks you !! 0 votes 0 votes Please log in or register to add a comment.
