S-I: Motion of centre of mass depends on external forces applied on it
S-II: The motion of the centre of mass of the body is called the translational motion of the body

View answer and explanation

Correct option: A

Both S-I and S-II are correct

The correct answer is Both S-I and S-II are correct because the motion of the center of mass is determined by external forces, and this motion is called translational motion.
