The energy required to dislodge electron from excited isolated H-atom,IE=13.6eV is
(3)<13.6eV and >3.4eV

Option (4) <3.4eV is correct.
E1 = 13.6 eV
Energy of the first orbit is -13.6 eV.
The lowest excited state of the hydrogen atom has the electron in the second orbit, thus energy required is equal to 3.4 or less than 3.4 (≤3)
