A disk, a hoop, and a solid sphere are released at the same time at the top of an inclined plane. They are all uniform and roll without slipping. In what order do they reach the bottom?

\( \text{Solid sphere: } I = \frac{2}{5}mR^2, \quad \text{Solid disk: } I = \frac{1}{2}mR^2, \quad \text{Hoop: } I = mR^2 \)

- **A.** hoop, sphere, disk.
- **B.** hoop, disk, sphere.
- **C.** sphere, disk, hoop.
- **D.** disk, hoop, sphere.
- **E.** sphere, hoop, disk.
