कौन-सा संबंध सममित नहीं है?
Which relation is not symmetric?
Explanation opens after your attempt
D. ({(1,2),(2,3),(3,2)})
Concept
In option D, ((2,3)) is matched by ((3,2)).
Why this answer is correct
But the reverse of ((1,2)), which is ((2,1)), is missing.
Exam Tip
If even one pair is missing its reverse, the relation is not symmetric. चरण 1: विकल्प D में ((2,3)) के साथ ((3,2)) है। चरण 2: लेकिन ((1,2)) का उल्टा ((2,1)) नहीं है। चरण 3: एक भी युग्म का उल्टा गायब हो तो संबंध सममित नहीं रहता।
