Solution

The correct options are
B Kinetic
D Mechanical
As the spinning wheel is slowing down, it is losing its kinetic energy. The Mechanical work on the wheel is due to the other spinning wheel. As they slow down, there will also be a decrease in the mechanical energy of the system.

Option $A$ and $C$ are correct.
