Momentum is mv...calculate V for each case...multiply with given mass.
just multiply and take the maximum answer
Option 3 --- equate 1/2*m*v^2 with given data to get V
option 4 --- use V^2 = 2*g*1km

as the formula of momentum is p=mv. Substitute the values and find out v and get an eqn using the values and the highest value will be your result
