the image of rectangle ABCD?

A figure shows rectangle ABCD and rectangle A prime B prime C prime D prime. Rectangle ABCD is oriented with point A in the upper left-hand corner, followed clockwise by points B, C, and D. Rectangle A prime B prime C prime D prime is positioned below and to the right of rectangle ABCD. It is oriented with point A prime in the bottom right-hand corner, followed counterclockwise by points B prime, C prime, and D prime. The figure also includes four lines of reflection. The first line is vertical, the second line is horizontal, the third line is diagonal from bottom left to top right, and the fourth line is diagonal from top left to bottom right.

A.
line 1

B.
line 2

C.
line 3

D.
line 4

Line 1, the vertical line, would make rectangle A' B' C' D' the image of rectangle ABCD.
