Answer:
C. Impulse = F*t=(m*a)*t= m*(a*t) = m*Dv= D(Momentum) (“D” here’s mean Delta so change in)
Step-by-step explanation:
In fact, the impulse is equal to the change in momentum of an object.
Impulse is defined as the product between the force (F) and the time (t):

however, the force is defined as the product between mass (m) and acceleration (a):

But the product a (acceleration) times t (time) is equal to the change in velocity of the object:

And this is exactly the definition of change in momentum:
