According to the bohr model "The lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.
By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr theory amended the atomic structure model.
He also showed that each orbit (shell) has a fixed energy. Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.
According to Rydberg formula
1/λ = R [1/ni² - 1/nf²]
λ = wavelength
R = Rydberg constant
ni & nf are integers or principal quantum numbers where nf > ni
So if we want wavelength(λ) to be shortest, then 1/nf should be zero.
In this way , it depends on nf and not on ni
That's why the lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

B- Carbon nitrogen and oxygen. All organisms are made up of carbon, oxygen is essential to breath, and nitrogen makes up most of earth's atmosphere.
Number 2 is Blackland Prairies
The Blackland Prairies region is named for the deep, fertile black soils that characterize the area.
