A vertex at (-5, 25) does, indeed, create a parallelogram.

BUT, (-5, 25) is not one of the answer choices.


A vertex at [spoiler](15, 25)[/spoiler] also creates a parallelogram.

Answer: E

Connect the three dots.
Now to form a parallelogram you can make any one of the lines of the triangle the diagonal of the parallelogram.

You will now get three possible coordinates for the 4th vertex of the parallelogram : (-5,25) , (15,25) , (-5,5)

The only one available in the options is (15,25) which is E.
