Outermost electronic configuration of four elements (I), (II), (III), (IV) are given below:
(I) \( 3 \mathrm{~s}^{2} \)
(II) \( 3 s^{2} 3 p^{1} \)
(III) \( 3 \mathrm{~s}^{2} 3 \mathrm{p}^{3} \)
(IV) \( 3 s^{2} 3 p^{4} \)
The correct order of first ionization enthalpy for them is:
(a) (I) \( \) (II) \( \) (III) \( \) (IV) (b) (II) \( \) (I) \( \) (IV) \( \) (III)
(c) (II) \( \) (IV) \( \) (I) \( \) (III) (d) (II) \( \) (I) \( \) (III) \( \) (IV)
