The correct answer is D. Kennedy’s theorem.
Stoke’s theorem, Gauss’s divergence theorem, and Green’s theorem are all fundamental theorems of vector calculus. They relate the integral of a vector field over a surface to the integral of its curl or divergence over a region enclosed by the surface.
Kennedy’s theorem is a theorem in differential geometry that states that the integral of a vector field over a closed curve is equal to the sum of the circulations of the vector field around the components of the curve.
It is not associated with vector calculus because it does not involve the curl or divergence of a vector field.
