A ring of mass m and radius R has three particle attached to the ring and it is rolling on the surface as shown in the figure. The ratio of kinetic energy of the system to the kinetic energy of the particle of mass 2m will be (speed of centre of ring is V0 and slipping is absent) :
(A) 2/5
(B) 1/2
(C) 3/1
(D) 2/3
