(D) In Boolean algebra,we evaluate the given expressions:$1$. For $A(B + \overline{B}) = A$: Since $B + \overline{B} = 1$,the expression becomes $A(1) = A$. This is correct.$2$. For $A + AB = A$: We can factor out $A$ to get $A(1 + B) = A$. Since $1 + B = 1$,the expression becomes $A(1) = A$. This is correct.$3$. For $A + 0 = A$: This is the identity law of Boolean algebra,which is correct.Since all three relations are correct,the correct option is $D$.
