Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: The first ionization enthalpy for oxygen is lower than that of nitrogen. Reason R: The four electrons in 2p orbitals of oxygen experience more electron-electron repulsion. In the light of the above statements, choose the correct answer from the options given below.

1. Both A and R are correct and R is the correct explanation of A
2. Both A and R are correct but R is NOT the correct explanation of A
3. A is correct but R is not correct
4. A is not correct but R is correct

Correct answer: Both A and R are correct but R is NOT the correct explanation of A
