The correct option is C R = {(x,y) ∈ A×B : y is one more than twice of x}
We should first compare the terms and see what is the relation between the terms.
Terms of Set A = {2,6,5,4}
Terms of Set B = {5,13,11,9}
If we take terms of A as x and terms of B as y,
y = 2x + 1
In Set-Builder form we can write it as :
R = {(x,y) ∈ A×B : y is one more than twice of x}
