(A) The successive ionisation energies are $801$,$2430$,$3660$,$25000$,and $32800 \ kJ \ mol^{-1}$.There is a very large jump in energy between the $3^{rd}$ and $4^{th}$ ionisation energy (from $3660$ to $25000 \ kJ \ mol^{-1}$).This indicates that the $4^{th}$ electron is being removed from a stable noble gas core,meaning the element has $3$ valence electrons.Elements with $3$ valence electrons belong to Group $13$,which is Boron $(B)$.
