Least-sided shape

What is the least sided shape in this image? It must be a closed figure.

The D with only 2 sides?

Are these shapes supposed to be orthographic projections of 3 dimensional objects? And we are supposed to figure out which 3D shape would have the smallest number of sides? Is that the puzzle?

Objects have faces, vertices and corners not sides.
Gatel solved it.

LOL, my instinct was to say the frame around the figures, but your suggestion is even better! 🙂

what counts as a side on a D. Clearly the line on the left, but the curved line on the right is all one 'side'?

The nut strikes again!

I guess that means that a circle has no sides, nor does a sphere (ball to you).

The C. Depending on whether you count curves as sides, it's either one side, or none.

The C isn't a closed shape and is therefore not up for consideration.

Sorry, I overlooked that.

I don't think a curve counts as a side, or else it would count as an infinite number of sides, in which case the answer is E) none of the above.

If we don't count anything with a curved side, it would be the closed part of the A, which is a triangle.

Actually the curve for D isn't a curve, if you look closely, you can see the pixels, which shouldn't be possible for a curve. Therefore, the frame is the least sided figure in the picture.
