You know electric field strength is V/m, and a volt is J/C, so the electric field strength is J/(C*m). This makes the fact that a C is appearing in the numerator of option D look extremely suspicious.
For a more rigorous approach the general idea would be to decompose V/m into SI base units, and decompose each of these options into SI base units. A comparison would then show which units have the same dimension, and which don't, since two units with the same SI base unit decomposition must be equivalent.
That means knowing that C = A/s, J = N*m, N = kg*m/s^2, etc.
