Regarding this post, I have two notices. 

    1.  If the problem is asking "which statement is true", the list of options to choose from must follow,

        but it is not a case with this post.



    2.  I perfectly understand that the expected answer is "the lines remain parallel",  but the problem

        MUST say that the rotation 90 degrees is about the common center.


        Otherwise, it may happen that the two parallel lines will become coincide.
