• A. The ionization potential of hydrogen, second member of Balmer series and third member of Paschen series.
• B. The first member of the Lyman series, third member of Balmer series and second member of Paschen series.
• C. The series limit of Lyman series, third member of Balmer series and second member of Paschen series.
• D. The series limit of Lyman series, second member of Balmer series and second member of Paschen series.

Answer 1
