As we learnt

 

Ionization Potential -

Ionization enthalpy is also known as ionisation potential (IP).Since it is minimum potential difference required to remove the outermost electron from an isolated gaseous atom to form gaseous ion.

-

The first ionization energy refers to the energy it takes to remove one electron from an atom.

It mainly depends on the electrostatic attraction between the positive protons in the nucleus and negative electrons—if protons and electrons are more attracted to each other, then the first ionization energy would be higher, and vice versa. Further, if the outermost orbitals are half-filled or fully filled, then these elements have the first ionisation energy higher than other elements.

Nitrogen has half-filled electronic configuration.

Therefore, Option(3) is correct
