Solution

The correct option is A $(Z - 1), (Z + 1)$
Noble gases belong to group 18. Atoms with ( Z-1 ) will belong to group 17 which comprises elements that are highly electronegative. These group 17 elements form ionic compounds with highly electropositive elements of group 1 ( here, Z + 1 ).
So, the correct option is '( Z - 1 ), ( Z+ 1 )'.
