Options
External force
Sum of the internal forces

Solution
The rate of change of total momentum of a many-particle system is proportional to the external force on the system.
Explanation:
Internal forces, regardless of their direction, are incapable of altering the total momentum of a body. Hence, the rate of change in total momentum of many particle systems is proportional to the external force on the system.
