A circle is a plane folded on itself so the answer is technically 0 holes. But first what is a hole?

a sphere is a plane folded in on itself, and spheres have no (one-dimensional) holes. but spheres do have a two-dimensional hole, which is basically a way of saying they’re hollow.
but a circle is a line folded in on itself, and lines have one (one-dimensional) hole.
