Which is the correct statement as per Law of polygon of forces?

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

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

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

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