The best way is to break all secondary units into the primary (base) units.
For example, N is a secondary unit which can be broken down into m kg s^-2, and so on.
and joule is N-m, or to the base, m^2 kg s-2
So you can compare the base units to see if they are equivalent.
I think the correct answer from the choices listed above is option D. The best way to determine whether j/m^2 and m*s^2/n are equivalent units would be to express them both in terms of si base units. Hope this answers the question. Have a nice day.
