							Transition energy (∆E) = kZ2 (1/(n_1^2 ))-  (1/(n_2^2 )) = hc/λ
Ie, ∆E ∝ 1/λ

							Acc to rydberg formula we can say tht wave no is inverse of wavelengthAnd waveno is directly proportional to z which is atomic no or can say no of protondSo wavelength of a spectral line is  inversely proportional to nuclear charge of atom( no of protond or atomic no) So b part is ansC part is also the correct answer bcoz acc to rydberg formula 1/ wavelength when goes to right side will came up and diff in energy levels came downside on rhs.... so they are inversely proportional .alsoHence ans of ques is both b as well as c part
