Considering Bohr's atomic model for hydrogen atom :
(A)
the energy of H atom in ground state is same as energy of $\displaystyle \mathrm{He}^{+}$ion in its first excited state.
(B)
the energy of H atom in ground state is same as that for $\displaystyle \mathrm{Li}^{++}$ion in its second excited state.
(C)
the energy of H atom in its ground state is same as that of $\displaystyle \mathrm{He}^{+}$ion for its ground state.
(D)
the energy of $\displaystyle \mathrm{He}^{+}$ion in its first excited state is same as that for $\displaystyle \mathrm{Li}^{++}$ion in its ground state.
