Electronic configuration is the distribution of electrons of an atom in atomic orbitals, we can find the electronic configuration of any atom if we have the information of the number of total electrons that the atom has, for Vanadium, we have 23 electrons, let's set a electronic configuration for it:
1s2 2s2 2p6 3s2 3p6 4s2 3d3
Since the answers are a little confusing, I can't say for sure which option it is, but it must be the option that fits the configuration above.
