(C) In Boolean algebra,the variable $A$ can only take two values: $0$ or $1$.If $A = 0$,then $\overline{A} = 1$. Thus,$A + \overline{A} = 0 + 1 = 1$.If $A = 1$,then $\overline{A} = 0$. Thus,$A + \overline{A} = 1 + 0 = 1$.Therefore,for any value of $A$,the relation $A + \overline{A} = 1$ always holds true.
