• A. (i) and (ii) only
• B. (ii) and (iii) only
• C. (iii) and (i) only
• D. (i), (ii) and (iii)

Answer 1

The correct option is A

(i) and (ii) only

1. While rolling from a height, it possesses potential energy at first, and then it is converted to the kinetic energy of the body due to the force of gravity.
2. There is no heat energy released during rolling.

Hence, option A is correct.
