Hello winsomeThe only one that is true is E: three parallelograms that are known to be rhombuses are the one designated a rhombus and the two rectangles which are known to be squares.

A and C are never true: every rhombus is a parallelogram and every rectangle is a parallelogram.

B is false: at least two of the rectangles are squares, and hence are rhombuses.

D is false: the rhombus is not a square, and hence it's not a rectangle either.
