Answer:
B) the change in momentum.
Explanation:
The impulse is defined as the product between the force applied on an object (F) and the duration of the collision ( ):
):
 (1)
 (1)
We can rewrite the force by using Newton's second law, as the product between mass (m) and acceleration (a):

So, (1) becomes

Now we can also rewrite the acceleration as ratio between the change in velocity and change in time:  . If we substitute into the previous equation, we find
. If we substitute into the previous equation, we find

And the quantity  is equivalent to the change in momentum,
 is equivalent to the change in momentum,  .
