In pure rolling motion of a ring
a) It rotates about Instantaneous point of contact of ring and ground
b) Its centre of mass moves in translatory motion only
c) Its centre of mass will have translatory as well as rotatory motion

View answer and explanation

Correct option: C

a and b are correct

Option C (a and b are correct) is correct because in pure rolling, the ring rotates about the instantaneous point of contact, and its center of mass undergoes translational motion only.
