(B) { (2,1), (4,3), (5,7) }

Step-by-step explanation:

If the same x value goes to 2 different y values, it is not a function

(A) { (2,3), (2,5), (4,7) } the x value 2 goes to 3 and 5

(B) { (2,1), (4,3), (5,7) }

(C) { (3,-2), (2,4), (3,6) } 3 goes to - 2 and 6

(D) { (-1,4), (-1,5), (2,5) } -1 goes to 4 and 5
