Which of the following is not the correct increasing order of ionisation energy?

The energy required to remove an electron of a gaseous atom from its ground state is called

The successive $5$ ionisation energies of an element are $800, 2427, 3658, 25024$ and $32824 \ kJ/mol$,respectively. By using the above values,predict the group in which the above element is present:

In the second period of the modern periodic table,two elements $X$ and $Y$ have higher first ionization enthalpy values than the preceding and succeeding elements. $X$ and $Y$ are respectively

The first ionisation potentials $(eV)$ of $Be$ and $B$ respectively are :-

Which of the following electrons should have the highest value of ionisation energy (for the same value of the principal quantum number)?
