Does there exist a regular simple closed curvey in the plane with total curvature less than 2, i.e. such that ſy ñ ds < 2π ? Select one: O a. Yes, there exists such a curve. In fact, there exists a curve with these properties with constant curvature. O b. Yes, there exists such a curve, but any such curve has non-constant curvature. O c. Yes, there exists such a curve, but any such curve is not convex. O d. No, no such curve exists, by the Jordan curve theorem. Oe. No, no such curve exists, by Hopf's Umlaufsatz. O f. No, no such curve exists, by Fenchel's theorem. O g. No, no such curve exists, by the isoperimetric inequality. Oh. No, no such curve exists, by Green's theorem. O i. No, no such curve exists, by the four vertex theorem. O j. No, no such exists, Gauss' Theorema Egregium. Ok. No, no such curve exists, by the Gauss-Bonnet theorem.
