As per Bohr model,
(I) minimum energy required to remove an electron from ground state of doubly ionized `Li` atom `(Z=3)` is `122.4eV`.
(II) energy of transition `n=3` to `m=2` is less than that of `m=2` to `n=1`.
(III) minimum energy required to remove an electron from ground state of singly-ionised He atom `(z=2)` is `27.2eV`
(IV) A Trasnsition from state `n=3` to `n=2` in a hydrogen atom result in `U-V` radiation
A. `II,III,IV`
B. `I,II`
C. `II,III`
