• A. Rest
• B. Motion
• C. Vibration
• D. Oscillation

Answer 1

The correct option is A

Rest

Explanation for correct option:

A: Rest

1. If an object does not change its position with respect to its surroundings over time, it is said to be at rest.
2. E.g. A table lying in a room is at rest with respect to the walls of the room.

Explanation for incorrect option:

B: Motion

1. We know that the body change position with respect to time then we can say that the body is in motion.
2. The measure of motion is the quantity of motion, which is derived from both the velocity and the quantity of matter.
3. The movement of air in and out of our lungs is an example of motion.

C: Vibration

1. Vibratory motion occurs when one part of the body remains stationary while the rest moves back and forth.
2. For example, When humans breathe, their chest expands and contracts.

D: Oscillation

1. The to and fro motion of an object from its mean position is known as oscillatory motion.

Thus, A body whose position with respect to the surroundings does not change is said to be in a state of rest.
