The element that has the least tendency to show the inert-pair effect ...
Inert pair effect is the tendency of outermost 2 e- of s orbital to remain unshared. It increases down the group bcoz as we go down the group the size of element increases so that there will be poor shielding of electrons and it can easily share or donate its e- but the size of N2 is small and s orbital is more close to nucleus so it will be difficult to remove e- from it hence N2 has least tendency to show inert pair effect. Hope it helps.

The element that has the least tendency to show the inert-pair effect ...
Explanation:
The inert-pair effect is the tendency of heavier elements of the p-block to exhibit a lower oxidation state. The inert-pair effect is observed in the elements of groups 13, 14, 15 and 16. The elements having the highest tendency to show the inert-pair effect are Pb, Sn, and Sb.
The inert-pair effect is due to the difference in energy between the 6s and 5d orbitals of the post-transition metals. In the heavier elements, the energy difference between the 6s and 5d orbitals increases, making it more difficult for the 6s electrons to participate in chemical bonding. As a result, the oxidation state of the element decreases.
Reason for Option D:
Nitrogen (N) is not a post-transition metal. It is a non-metal that belongs to group 15 of the periodic table. The inert-pair effect is not observed in non-metal elements. Therefore, option D is the correct answer.
Conclusion:
In conclusion, the inert-pair effect is observed in post-transition metals and refers to the tendency of these elements to exhibit a lower oxidation state due to the difference in energy between their 6s and 5d orbitals. Nitrogen (N) is not a post-transition metal and does not exhibit the inert-pair effect.
