Answer
Reactive metal : (a.)
Reactive non-metal : (c.)
Work Step by Step
(a.) has configuration of $ns^{2}$. It will be reactive and lose 2 electrons to achieve the noble gas configuration. So it is a reactive metal.
(c.) has configuration of $ns^{2}np^{6}$. It will be reactive and gain 1 electron to achieve noble gas configuration. So it is a reactive non-metal.
