Take any two consecutive sides and draw the resultant according to triangular law. This resultant will be equal and opposite to the third force which is taken in order. Hence, the net of the three forces is zero. So, disagree is the right option.

Here, it says NOT in equilibrium.
So, the given answer is correct.
So, the given answer is correct.

Answer B is correct.
In triangle law of forces, two forces acting at a point be represented by two sides of triangle taken in order then, third side taken in opposite order represents their resultant.
So for equilibrium resultant force is neutralised by equal and opposite force.
So for equilibrium three side must be in same order.

If we delete "taken" in order, then the option A will correct.

If the forces are in order that means they must be of same nature, then how can they will be in equilibrium.
Since, we know that a/c to triangle law, one of the sides of the triangle must be of the opposite order to attain the equilibrium.

If there are in equilibrium then it is triangular law of forces.
