Mark the correct alternative in the following:

If R is a relation on the set A = {1, 2, 3, 4, 5, 6, 7, 9} given by xRyy = 3 x, then R =


Here, y = 3x;

If x = 1; then y = 3.


If x = 2; then y = 6.


If x = 3; then y = 9.


Therefore the required relation will be R = {(1, 3), (2, 6), (3, 9)}.


So, correct answer is D.
