If Points X and Y are two distinct points in the Coordinate Plane;which of the following can have more than one possible value?

A.Circumference of Circle with diameter XY
B.Area of Square with diagonal XY
C.Perimeter of Right Isoceles Triangle with one of the legs as XY
D.Area of Circle with Chord XY
E.Area of an equilateral triangle with base XY.

First of all this is a PS question.Please get it moved to the correct thread.Secondly,Typing the text version of a question always helps others help you.

Now coming down to the explannation:
XY shall remain constant and thus any option that relies on XY is ruled out.Contention is between C and D.
There could be multiple Isoceles triangles with different combinations and multiple circles as well.Any one listening?
