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

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