Explanation:
The line y=0 is the x-axis, so any reflection of a figure drawn above the x-axis will result in a figure below the x-axis. This limits your choices to A and B.
A reflection across the x-axis only changes the y-coordinates of the points, so choice B is incorrect.
_____
The correct picture is that of A. Each image point is as far below y=0 as the original point is above y=0. That is what we mean when we say "reflection over the line y=0."
