Answer: Option (d) is the correct answer.
Explanation:
Noble gases are the gases of group 18 which are helium, neon, argon, krypton, xenon and radon.
For example, electronic configuration of neon is [tex]1s^{2}2s^{2}2p^{6}[/tex]
These elements have completely filled shells so, they do not need to gain or lose an electron as they are stabilized.
As a result, noble gases become unreactive in nature.
Thus. we can conclude that noble gases is the name of the group of elements that are unreactive gases.
