Which of the following correctly orders the first ionization energies of the elements Li, B, Be, and C from lowest to highest? a)

\mathrm{Li}<\mathrm{Be}<\mathrm{C}<\mathrm{B}

\mathrm{Li}<\mathrm{Be}<\mathrm{B}<\mathrm{C}

\mathrm{Li}<\mathrm{B}<\mathrm{Be}<\mathrm{C}

\mathrm{Li}<\mathrm{B}<\mathrm{C}<\mathrm{Be}
