What is a statement of the principle of conservation of momentum?

1. AA force is equal to the rate of change of momentum of the object upon which it acts.
2. BIn a perfectly elastic collision, the relative momentum of the objects before impact is equal to their relative momentum after impact.
3. CThe momentum of an object is the product of the mass of the object and its velocity.
4. DThe total momentum of a system of interacting objects remains constant, providing no resultant external force acts on the system.
