If I am not wrong, the answer should be 2. Potential energy will convert to kinetic energy rolling down the ramp.
Potential energy(stored energy in the cylinder) ->(converted to) kinetic energy(rolling down the ramp.)
Or the answer key might be wrong.
But do remember that gravitational force/gravity acts on everything,whether it is flying or lying on the ground, or whether it is moving or stationary.
Hope this helps!
