Quizplus · Accepted Answer

The Balmer series corresponds to the transition of electrons from higher energy levels (n>2) to the second energy level (n=2). In the energy-level diagram shown, the transitions corresponding to the Balmer series are from n=3,4,5,6,... to n=2. These transitions are represented by the series labeled 2 in the diagram. Therefore, the correct choice is B.
