+1107 It depends on the size of the shape. If they are all super small, then any of them could, but my best guess would be square, and anyone, correct me if I am wrong about this. Please do.
+9466 For a shape to be inscribed in a circle, all the vertices have to be on the circle.
A square can be inscribed in a circle, like this:
Since a square is a rectangle, and a square can be inscribed in a circle, a rectangle can be inscribed in a circle. And since a square is a parallelogram, and a square can be inscribed in a circle, a parallelogram can be inscribed in a circle.
Note that a rectangle with different side lengths could also be inscribed in a circle. However, a parallelogram with non-right angles could not be inscribed in a circle.
An isosceles trapezoid can also be inscribed in a circle, like this:
All of the options could be inscribed in a circle.
