If potential energy of an electron in ground state is -13.6 eV. The energy of next higher state is:
a) -27.2 eV
b) -6.8 eV
c) -3.4 eV
d) none of these

please help me. Is it B?

If I understand you question, yes, B is the correct answer. The energy of the levels are negative and go to zero when the electron is at infinity; i.e., when the atom is ionized. The NEXT high level would be C after B. I hope this helps.
