This is a DS question from the Manhattan GMAT Geometry Question Bank and I don't agree with answer:

Is quadrilaterial ABCD a rhombus?

1) Line segements AC and BD are perpendicular bisectors of each other.

2) AB = BC = CD = AD

The answer Manhattan provides is D.

Shouldn't the answer be E because the quadrilaterial could also be a square based on either 1) or 2) above? So it's not definitely a rhombus, but it could be?
