PLEASE HELP ASAP WILL MARK BRAINLIEST

  A (the marked answer is correct)

Step-by-step explanation:

The result of a single refection will look like the reverse of the letter Z, so the only possibilities are choices A and C.

Since the horizontal lines are still horizontal, the reflection must be across a horizontal or vertical line. If the reflection is across a horizontal line, the image will be vertically aligned with the preimage. If the reflection is across a vertical line, the image will be horizontally aligned with the preimage.

Choice A is horizontally aligned with the preimage. Choice C is not aligned either way. (It is a "glide reflection.")

Image A is the result of reflection across the y-axis.
