Three objects, A: (a solid sphere), B: (a thin circular disk) and C: (a circular ring), each have the same mass \(\mathrm{M}\) and radius \(\mathrm{R}.\) They all spin with the same angular speed about their own symmetry axes. The amount of work (\(\mathrm{W}\)) required to bring them to rest, would satisfy the relation:

1. \(\mathrm{W_C}>\mathrm{W_B}>\mathrm{W_A} ~~~~~~~~\)
2. \(\mathrm{W_A}>\mathrm{W_B}>\mathrm{W_C}\)
3. \(\mathrm{W_B}>\mathrm{W_A}>\mathrm{W_C}\)
4. \(\mathrm{W_A}>\mathrm{W_C}>\mathrm{W_B}\)
