Solution

## The correct option is C A × B = {(1,2), (1,3), (3,2), (3,3), (5,2), (5,3)} B × A = {(2,1), (2,3), (2,5), (3,1), (3,3), (3,5)}Given that A = {1,3,5} and B = {2,3} A × B = {1,3,5} × {2,3} = {(1,2), (1,3), (3,2), (3,3), (5,2), (5,3)} B × A = {2,3} × {1,3,5} = {(2,1), (2,3), (2,5), (3,1), (3,3), (3,5)}
