Can someone explain how to solve this?

You must be very creative in these questions:) Try to think of as many formulae as you know for each of the given qualities.
Ex.
Work = Force * distance (units: Nm = J)
Momentum = Force * time (units: Ns)
In option B, we are given momentum * velocity, so Ns * m/s = Nm
As we can see, Nm is the definition of Joule, so B gives us Newton-meters and thus Joules:)
