Llianna rotated trapezoid WXYZ 180° about the orgin

What is the correct set of image points for trapezoid W’X’Y'Z'?
W(4, -2), X (3,-4), Y (1, -4), Z'(0, -2)
W(4,2), X (3, 4), Y (1, 4), Z'(0, 2)
W(-2, -4), X(-4,-3), Y(-4,-1), Z(-2, 0)
O W (2, 4), X(4,3), Y (4,1), Z (2,0)

It is Letter B. To me that is what is correct
