According to Bohr's model, the highest kinetic energy is associated with the electron in the

first orbit of H atom

first orbit of

\ce{He+}

second orbit of

\ce{He+}

second orbit of

\ce{Li^2+}

Answer and worked solution

Official answer: B

In the Bohr model, $KE_n=-E_n=13.6\,\dfrac{Z^2}{n^2}$ eV.
