Which is the correct statement about law of polygon of forces?

If any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon taken in order, then the forces are in equilibrium

If any number of forces acting at a point can be represented by the sides of a polygon taken in order, then the forces are in equilibrium

If any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon, then the forces are in equilibrium

If a polygon representing forces acting at a point is closed then forces are in equilibrium

Engineering Mechanics
According to Newton's first law of motion,

Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force

The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts

None of these

To every action, there is always an equal and opposite reaction
