We need to rank the objects according to the magnitude of their momentum.

We know momentum , $P = m\times v$ { here m is mass and v is velocity }

Momentum of object A , $P_A = m v.$

Momentum of object B , $P_B= \dfrac{m}{2}\times4v=2\ mv.$

Momentum of object C , $P_C= 3m\times\dfrac{v}{3}=mv.$

Now, we can rank them in order of their magnitude of momentum .

$P_B>P_A=P_C$ .

Hence, this is the required solution.
