Solution

The correct options are
A Kinetic
B Total
C Internal
D Mechanical
As the wheel starts its motion as it comes in contact with the other wheel, it will lead to increase in the kinetic energy and the total energy of the wheel B as initially it was at rest.
Due to this change in the energy, there will also be a change in the internal energy of the wheel as it starts to spin or rotate. The mechanical energy of the wheel is due to its mechanical work done. As the wheel continues to spin, the amount of mechanical energy will also increase.

Therefore all options are correct. It will increase all the forms of energy.

Q. A spinning wheel is brought in contact with an identical wheel spinning at identical speed. The wheels slow down under the action of friction. Which of the following energies of the wheel decreases?

A uniform wheel of radius R is set into rotation about its axis at an angular speed $ω$ . This rotating wheel is now placed on a rough horizontal surface with its axis horizontal. Because of friction at the contact, the wheel accelerates forward and its rotation decelerates till the wheel starts pure rolling on the surface. Find the linear speed of the wheel after it starts pure rolling.
