Answer: Choice C

Pentagon DEFGH is reflected about the y-axis.

Step-by-step explanation:

Let's focus on one point, say point G.

It's located at (1,3). Its corresponding image point is G ' (-1,3).

The rule [tex](x,y) \to (-x,y)[/tex] was used and this rule is for y axis reflections. The mirror line is the y axis itself. The other points of that preimage follow the same idea.
