The correct match of metal with emitted wavelength is given below:

\mathrm{(A) \mathrm{Li}: 670.8 \mathrm{~nm}(I)}

\mathrm{(B) \mathrm{Na}: 589.2 \mathrm{~nm} (II)}\\

\mathrm{(C) Rb: 780 \mathrm{~nm} (III)}\\

\mathrm{(D) Cs: 455.5 \mathrm{~nm} ( \mathrm{IV})}

Hence correct answer is option (1)
