Answer: OPTION A.

Step-by-step explanation:

By definition:

- When you reflect a figure, you flip it over a line of reflection, then, both figures will be in opposite directions.

- The image (which is the reflection) and the pre-image will have the same shape ad size.

- If a figure is reflected over the y-axis, then the sign of the x-coordinate is changed.

Keeping the above on mind, you can conclude that when a triangle is reflected over the y-axis the coordinates of the vertices are afectted as following:

- The y-coordinate is not changed.

- The sign of the x-coordinate is changed.

Then:

[tex](x,y)[/tex] → [tex](-x,y)[/tex]
