A composite wheel consists of a uniform solid disk of mass \(M\) and radius \(R\) fixed concentrically inside a thin circular rim, also of mass \(M\) and radius \(R\). The wheel rolls without slipping along a horizontal surface such that its center of mass moves with a constant speed \(v\). Which of the following correctly pairs the ratio of the wheel's rotational kinetic energy to its total kinetic energy, \(\dfrac{K_{\text{rot}}}{K_{\text{total}}}\), with the component that contributes more to the wheel's total kinetic energy?
