The total momentum of an isolated system is conserved during a collision, meaning that the total momentum before the collision is equal to the total momentum after the collision, assuming no external forces act on it. In this case, the billiard ball has an initial momentum of 3 kg⋅m/s.

After the collision with the three other billiard balls, the total momentum of the system (the original billiard ball and the three struck balls) will still be 3 kg⋅m/s. Therefore, the correct response is:

**3 kg⋅m/s**
