The energy levels of the hydrogen spectrum is shown in figure. There are some transitions A, B, C, D and E. Transition A, B and C respectively represent

Transition A(n=∞ to 1) :  Series limit of Lyman seriesTransition B (n = 5 to n = 2) : Third spectral line Transition C (n = 5 to n = 3) : Second spectral line
