The forces which meet at one point and have their lines of action in different planes are called A. Coplanar non-concurrent forces B. Non-coplanar concurrent forces C. Non-coplanar non-current forces D. Intersecting forces

Therefore, a non-coplanar concurrent force is a force that acts at a single point and does not lie in the same plane as another force.

Option A is incorrect because coplanar forces are forces that lie in the same plane.

Option C is incorrect because non-coplanar non-concurrent forces are forces that do not lie in the same plane but do not act at a single point.

Option D is incorrect because intersecting forces are forces that meet at a point but do not necessarily act at the same point.
