Answer:
(a)
Explanation:
Technically, throughout the universe, nothing is at rest. Everything is always in motion with respect to something. Such as, all things on Earth are in motion as the Earth revolves around the sun. The entire solar system is in motion as it is a part of The Milky Way Galaxy which is moving as well, and so on.
But, if a body is at rest with respect to an observer, it means that it is not moving at all in the eyes of the observer. But again, if a body is determined to be at rest or not, purely depends on the perspective of the observer
