Answer:

see below

Explanation:

Of your remaining answer choices, the only one that shows a reflection (not a translation) is the one below. It has the orientation of the figure reversed (side lengths shortest-to-longest are CCW instead of CW).

The reflection over y=x reverses the coordinates: (x, y) ⇒ (y, x), so the vertices become ...

  • (1, -3) ⇒ (-3, 1)
  • (3, -2) ⇒ (-2, 3)
  • (4, -5) ⇒ (-5, 4)
