Answer: The correct option is
(C) (0, 3).
Step-by-step explanation: We are given to choose the pair of numbers that is not a solution to the following equation :

If a point is not a solution to the given equation, then it will not satisfy the equation.
Option (A) : The given point is (x, y) = (1, 3).
We have

So, (1, 3) is a solution to the given equation.
Option (B) : The given point is (x, y) = (2, 1).
We have

So, (2, 1) is a solution to the given equation.
Option (C) : The given point is (x, y) = (0, 3).
We have

So, (1, 3) is NOT a solution to the given equation.
Thus, option (C) is CORRECT.
