I think that they are asking for hydrogen , as the energy for H atom is as -13.6/n² eV , so for ground state N=1 , so ground state energy is -13.6 eV ,so to remove the electron we have to give e the same amount of positive energy , and if we convert 13.6eV into joule just multiply by 1.6*10^-19 = and result is C option , that's how it comes
