which figure represents the image of trapezoid lmnp after a reflection across the x-axis?

figure a
figure b
figure c
figure d

Consider trapezoid LMNP with vertices at points (-2,3), (-2,6), (-1,6) and (-1,4), respectively.

The reflection across the x-axis has a rule:

(x,y)→(x,-y).

Then

As you can see points L', M', N' and P' form trapezoid L'M'N'P' and this is exactly figure A.

correct choice is A.
