Answer:

B. No net external force acts on the system

Momentum is conserved when the mass of the system of interest remains constant during the interaction in question and when no net external force acts on the system during the interaction.

Answer:

A system must meet two requirements for its momentum to be conserved: The mass of the system must remain constant during the interaction. As the objects interact

(apply forces on each other), they may transfer mass from one to another; but any mass one object gains is balanced by the loss of that mass from another.
