The \sigma 2 p_z orbital is the LUMO of \mathrm{B_2} molecule because it is the orbital that is most easily excited. This is because the \mathrm{\sigma 2 p_z} orbital is relatively high in energy, and it is also the orbital that is most exposed to the environment. This means that it is more likely to interact with other molecules and to be excited to a higher energy level.
