Question
The relation R defined in A = {1, 2, 3} by a Which of the following is false
 R ={(1, 1), (2, 2), (3, 3), (2, 1), (1, 2), (2, 3), (3, 2)

 Domain of R = {1, 2, 3}
 Range of R = {5}
The correct answer is: Range of R = {5}
To find the false statement from the given option for the given relation.
R={(1,1),(2,2),(3,3),(2,1),(1,2),(2,3),(3,2)} when a=1, 2, 3.
$As we can see, =R$
Domain $={1,2,3}$ Range $={1,2,3}$
Hence, Range of R = {5} is the wrong option.
