The Law of Polygon of Forces states that A. If a polygon representing the forces acting at point in a body is closed, the forces are in equilibrium B. If forces acting on a point can be represented in magnitude and direction by the sides of a polygon taken in order, then the resultant of the forces will be represented in magnitude and direction by t C. If forces acting on a point can be represented of a polygon taken in order, their sides of a polygon taken in order, their resultant will be represented in magnitude and direction by the closing side D. If forces acting on a point can be represented in magnitude and direction by the sides of a polygon in order, the forces are in equilibrium

The correct answer is: A. If a polygon representing the forces acting at point in a body is closed, the forces are in equilibrium.

The Law of Polygon of Forces states that if a polygon representing the forces acting at a point in a body is closed, the forces are in equilibrium. This means that the sum of the forces acting on the point is zero.

Option B is incorrect because the resultant of the forces will not always be represented by the closing side of the polygon. For example, if the forces are all equal in magnitude and opposite in direction, the resultant will be zero and the polygon will not be closed.

Option C is incorrect because the sides of a polygon taken in order do not always represent the forces acting on a point. For example, if the forces are not all collinear, the sides of the polygon will not be parallel to the forces.

Option D is incorrect because the forces acting on a point can be represented in magnitude and direction by the sides of a polygon in order even if the forces are not in equilibrium. For example, if the forces are all equal in magnitude and opposite in direction, the polygon will be a straight line and the forces will be in equilibrium.
