Answer is D. (3, 4) (0, 6) ( -2, 1)

Explanation;

The rule for a reflection over the y -axis is (x,y)→(−x,y) .

So we find the current coordinates and change the x value to opposite sign and leave the y value the same. This is because when you reflect across the y axis you go from a positive quadrant (I) to negative (II) or a negative (II) to a positive (I).

A = -3, 4 ➡️ A’ = 3, 4

B = 0, 6 ➡️ B’ = 0, 6

C = 2, 1 ➡️ C’ = -2, 1

I gave you a graph as a visual I hope it helps
