          Answer & Explanation
         Answer: D) least reactive nonmetals         
         
Explanation: Helium (He), Neon(Ne), Argon(Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) and Ununoctium (Uuo) are present group 8A.
 
They have fully filled orbitals and hence are most stable amongst all the elements in the periodic table and are considered as least reactive least reactive non-metals.
