Detailed Solution

Concept: When a body's posture doesn't fluctuate over time, it is considered to be stationary or at rest. In other words, the body's displacement, velocity, and acceleration are all equal to zero. A body must meet certain requirements to be at rest, according to Newton's first law of motion.
A body is said to be stationary or at rest if its position does not vary over time. Until and unless an external, unbalanced force acts on a body, Newton's first law of motion states that it will continue to be in its current state of motion or rest. Therefore, in the general case, the forces acting on the body at rest balance each other out if it must stay at rest.
The body does not experience any acceleration as a result of the external pressures since they cancel one another out.
Forces do not have to come into contact with the body in order to alter the body's resting state. For instance, a magnet can draw a nearby iron coin that is at rest, altering its state of rest.
Hence, the correct option is 3.
