• A. (a) - (iii), (b) - (ii), (c) - (i)
• B. (a) - (ii), (b) - (i), (c) - (iii)
• C. (a) - (ii), (b) - (iii), (c) - (i)
• D. (a) - (iii), (b) - (i), (c) - (ii)

Answer 1

The correct option is C (a) - (ii), (b) - (iii), (c) - (i)

1. When a body moves in a circular path with respect to time, it is known as circular motion. e.g. the tip of minute hand.
2. When a body moves in a straight line with respect to time, it is known as linear motion. e.g the stone falling from a height.
3. When a body moves about its own axis, it is known as rotational motion. e.g. the wheel of the sewing machine.
