Correct Option: B

This is inertia of direction. It is the ability of body to be in a state of direction of motion .for example sun holds planets in a fixed elliptical path .this is one of the examples of inertia of direction. Inertia of direction is non-existent however inertia only apply to a body at rest or moving with a constant velocity. It is the property possessed by a body to resist change. In other way we can say that if a body moves in a particular direction under the action of a force and if the force is removed then the will continue to move in the same direction unless stopped under the action of another opposing force for a body at rest it under the inertia of rest whereas inertia of motion is for bodies in motion.
