Consider the following statements,
(P) IE (I) of nitrogen atom is more than IE(1) of oxygen atom.
(Q) Electron affinity of oxygen is less than sulphur atom.
(R) Electronegativity of an atom has no relation with its ionization enthalpy and electron gain enthalpy.
Which of the above statements are correct?

The third statement is untrue because the ionisation energy can be considered as a kind of counter property to electronegetivity in that a low ionisation energy implies that an element readily gives electrons to a reaction, whereas a high electronegativity implies that an element strongly seeks to take electrons in a reaction.
