Correct Answer

C

Explanation

One of the conditions of equilibrium r three coplanar non-parallel forces that their linesof action must meet at point (i.e. concurrent).
When three coplanar non-parallel forces are in equilibrium, it means that the vector sum of these forces is equal to zero. In other words, the forces cancel each other out and there is no net force acting on the system.

In this situation, the forces must satisfy two conditions:

1. The vector sum of the forces in the horizontal direction is zero.
2. The vector sum of the forces in the vertical direction is zero.

If these conditions are met, it indicates that the forces are balanced and the system is in a state of equilibrium. This means that the object or system on which these forces act will remain at rest or continue to move with a constant velocity.

It's important to note that the forces being coplanar means that they all lie in the same plane, and being non-parallel means that they are not aligned in the same direction.
